Android includes a large number of directories, but here the question arises - which folders can be deleted and which cannot be touched?

Read the article before deleting folders.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Folders Android

The folder list may differ depending on the Android version... Some applications can create their own directories in memory - for example, instant messengers. However, in general, the list of folders on all versions of Android will be the same, so you just need to know what is stored in them.

• Cache - folder with temporary update files. If you are not going to update the system, you can delete it.
• data / app - setup files all third party applications. If you don't use them, you can delete them.
• data / data - settings, saving and other service information required for applications to work. If you are not using the installed programs, delete the directory.
• data / clipboard - data clipboard with the latest screenshots. It is not recommended to delete.
• data / dalvik-cache is the cache area for the java virtual machine that allows the phone to run APK files. Files must be cleaned regularly, but must not be deleted. (read)

The Documents folder contains a variety of documents. If you are not interested in their content, feel free to delete the directory. The same applies to the Bluetooth directory where the files received by this wireless technology are located.

Increase

The DCIM folder contains photos taken with the camera. If you don't have the photos you want, you can fearlessly erase the catalog. Will not affect Android work deleting the folders Images, Pictures, Musi, Audio, etc.

Folders that cannot be deleted

There are folders in Android that absolutely cannot be deleted, since without them the system will not work correctly. Remember these names:

• efs - Information about IMEI, Mac, Bluetooth and Wi-Fi.
• etc - configuration files used when booting the system and various firmware processes.
• lib - libraries required for the operation of programs and modules.
• mnt - images of mounted systems.
• proc - key information about installed system.
• sbin - executable files of all programs involved in system management.
• sys - current system configuration.

In no case should you delete the system folder with all its subdirectories. System is the backbone of the system, so if you delete any data from here, you will be flashing the phone again.

Removal methods

To delete system folders, you need superuser rights - root. If you don't have them, then you definitely won't be able to break Android. If available, you need to be extremely careful - deleting important system files will lead to the fact that you have to flash the device again.

If you figured out which folders can be painlessly deleted, then proceed to clearing memory using standard functions:

1. Open the Android main menu and launch the file browser (file manager).
2. that you can delete. Click on it and hold your finger.
3. When the menu appears, choose Delete.

Shown is a multi-choice manager option. The delete button is in this case at the top right in the form of a trash can icon.

The standard file manager does not display all files and android folders... To clean your device memory well, use ES File Explorer or another third-party file manager.

1. Launch ES File Explorer.
2. Choose what to clean - Internal Storage or a memory card.
3. Hold your finger on the folder you want to delete. Once it's checked, start highlighting other files and folders.
4. After selecting all the items to be deleted, click on the "Delete" button in the bottom menu.

You can not use file managers on Android, but simply connect your phone to your computer by selecting the media device mode, in which you can view and change the contents of the memory.

They often face the problem of memory overflow. Probably, there is no universal recipe for solving this trouble, although you can look for some practical advice, however, they are not systematized. Let's try to understand this issue and figure out how to free internal memory on Android.

Types of storage devices

So, first you need to understand what are in devices with the Android operating system. You need to know this in order to better understand the essence of the problem and what to do with it.

RAM, RandomAccessMemory or RAM

This is the so-called random access memory. This is where the operating system and software Android systems record all the necessary data for the smooth operation of the application, by the way, they calculate it quite quickly. It should be borne in mind that when the device is turned off or rebooted, the RAM is quickly cleared, the RAM necessarily requires a constant power supply.

Well, and, accordingly, the more memory, the more services and applications can be simultaneously launched on the device. The amount of memory also determines which resource-intensive applications you can run on your phone. When the whole volume random access memory is exhausted and there is not enough space for the new application you are trying to launch, you may receive a "Phone memory full" error. In principle, technologies do not stand still, and already from Android 2.2 and higher, the operating system itself determines what needs to be removed from memory, which applications can be closed in order to free up space. Today, many flagship devices have ample 1GB of memory. There are even 2 Gigabytes. Therefore, the question of how to free the internal memory on "Android 4.1.2" arises less often than in relation to more early versions... If we consider more on Android, tablets and smartphones, then they are basically 512 MB or slightly more than 768 MB (a rather non-standard size).

In fact, progress does not stand still, everything is improving, because just a couple of years ago, most Android devices had only 256 megabytes of RAM and instructions on how to free up internal memory on Android 2 were in great demand.

ROM, ReadOnlyMemory or ROM

It is read-only. What is stored in it does not change and is recorded at the factory or when reinstalled operating system, when flashing. The ROM is divided into sections to perform various internal functions.

Interal Storage (Interal Phone Storage)

Myself internal storage... This is where all the data and applications that the smartphone user enters and tablet computer... An internal drive is an analogue of a hard drive in a personal computer. Of course, when we write various applications to the device, the memory decreases, and it is not difficult to increase it - just delete the unnecessary. You can find out how much of the built-in storage and the availability of free space by seeing them in the settings of the device. Thus, often the answer to the question of how to free the internal memory of "Android" is to clear the internal storage.

or ExternalStorage

This is the so-called removable memory. The size of the memory card depends on the card you have chosen, however, it is necessary to take into account whether your device has the necessary spot, and whether the device supports it. ExternalStorage can be compared to an external hard drive for personal computer... And the amount of free space and occupied space can also be seen in the settings of your gadget. It is good to store multimedia data on such a card: music, films, photos, pictures. By the way, already from Android 2.2 and higher, you can transfer all applications, user-installed to a memory card, this significantly saves space on the internal storage. If you decide to replace the memory card, do not forget to unmount it first, and only then remove it.

Android smartphones: how to free up internal memory?

Many users, after being more or less accustomed to their gadget, begin to install, stuff their device with various applications, scripts, and modify programs in every possible way. And someday the message "Phone memory is full" will appear, especially if the model is not the most expensive, and there is not much internal memory in it. Part of the problem lies in the RAM. It is very easy to clean it - through the device settings or download an additional utility. So, when the internal memory of the gadget is full, a message will appear stating that there is not enough memory. In principle, you can constantly clear the internal storage, delete applications that you no longer use, but the time will come when this message will appear more and more often. Quite a lot of space is occupied by various updates that come for GooglePlay. By the way, you can transfer some of the programs to a memory card using a special Link2SD program. InternalStorage is accessed with Root rights. These actions are also good at clearing memory. You still need to clean up the so-called they have the .rm extension, are stored in the datalocalmp folder and are constantly accumulating. For this action, you also need to have Root access and resort to the help of RootExplorer, plus files with the log extension are often accumulated in the same folder and contain error in their name - these are application errors, they also take up a lot of space. All these unnecessary files must be deleted.

What are the best measures to take?

But this is all a temporary cleaning of the device. What is a more thorough way to free up internal memory on Android? When installed on or a smartphone with an Android device, each program creates a file with the .dex extension in the datadalvik-cache directory. True, it happens that some system applications do not have such files.

It may seem strange that this program does not take up space. However, the reason is that along with these files in the phone memory there are files of the same name, but with the extension .odex. In principle, such files can be created, then there is no need to leave .dex files. To do this, you can install additional annex for example LuckyPatcher.

Now let's proceed directly to the steps that help answer the question of how to free up internal memory on Android 2.3.6 and in newer versions.

Let's see how much space the application takes - the "Properties" menu.

For example, this is 1.68 Megabytes, and, accordingly, the dex file occupies the same amount of memory, and the same amount will "weigh" the odex file that we created. Now you need to launch the LuckyPatcher application, select from the list desired application... Pinch (hold, not just click). It turns out You need to choose the first or second item. The program itself will create the odex files we need. Then we delete dex from the datadalvik-cache folder. The application now works fine and takes up 0 MB. This way you can free up memory for everyone. system applications... Thus, the instruction is carried out on how to free up internal memory on "Android 4.0" and other distributions.

A slightly different method is suitable for cleaning user applications. We chose an application, went to its folder on the memory card, we see the free space of this application. For example, there is 1.56 MB of free space, and the dex file is 1.68 MB. You can, in principle, move the desired application to the system directory and do the same as mentioned above, or simply select another application and leave it as it is. By the way, if you still move this application into user memory and create an odex file and then delete the dex file, then the application will work fine. But if you transfer it to a flash drive, then the odex file will be deleted, and the program will not work, then you will have to either reinstall it, or do a complete cleanup of dalvik-cache. Please note that not every program will work without dex files. This is typical for games or applications with dex up to 1.5 megabytes. This method is suitable only for applications that have less dex files than free memory space. As you can see, the steps to help answer the question of how to free up the internal memory on the "Adroid" are not particularly difficult.

How to clear android internal memory when android internal memory is full. In this article you will find out effective ways clearing the internal ROM (internal) memory of the android device and get rid of the message "internal phone memory is full".

Using mobile device sooner or later the question arises: how to clear memory on android... This problem can arise when you want to install an application, download something from the Internet, receive files via bluetooth, or your phone or tablet simply displays a message: the internal memory of the phone is full - we will tell you what to do. Cleaning your phone from trash has a positive effect on the speed of the entire device and applications.

After you have moved the necessary files to the memory card, you managed to partially clear the internal memory of the android. But that's not all, and if you want to free up even more space and forget about the error: the internal memory of the android is full, read the article to the end.

2. How to transfer applications to a memory card

How to transfer applications to a memory card in order to clear the internal memory of an android is a rather difficult task, since such an operation has some limitations. For its full implementation, you need to obtain administrator (root) rights by installing the necessary software, but at the same time you lose the warranty on your android device, and if you do something wrong, you can turn it into a brick. If you already have root access, install the application, with its help you can transfer applications to the memory card, even some pre-installed ones, but this may affect the correct operation of these applications and the system as a whole.

Most applications are automatically installed into the internal memory of the device, and without administrator (root) rights, they cannot be transferred. This can be done in "Settings" - "Applications", but this method is not the most convenient. There are quite a few programs in the Play Store application store with which you can transfer applications to a memory card. We suggest using a multifunctional application Android Assistant which includes 18 necessary tools to control android. You can download Android Assistant, as well as familiarize yourself with its capabilities in the article:.

Launch Android Assistant, go to the " Tools" and select the item "App2Sd".
The tab opens a list of applications that can be transferred to the memory card. After selecting applications, you are thrown into "Application Information", click here "To SD card".

You can clear the internal memory of android if you delete unnecessary applications... For convenience, we recommend a tool in Android Assistant - "Batch delete"- it allows you to select several applications to uninstall at the same time and show in which memory it is installed.

3. How to clean your phone or tablet from trash

Unlike the previous tasks, where at correct setting and performing the described actions you will not have to repeat them sometime, then you will need to use your knowledge of how to clean the android from garbage quite often. The good news is that when installing the necessary software, this process is very simple and fast.

You need to understand that garbage appears constantly: this is a cache from open pages on the Internet, running applications or their remnants after deletion, etc., therefore, if you periodically clean the android from garbage, then this not only allows you to clear the internal memory of the android, but also has a positive effect on the speed of applications and devices.

To solve the problem: how to clear the internal memory of android from garbage, we suggest using the application Clean master ... It is not only a very handy, simple and functional tool for cleaning internal memory, but also the best cleaner for android.

Launch the Clean Master application, select "Rubbish" and "Clear". After that, the application offers to do more advanced cleaning and warns that this section may contain the necessary data, so carefully select the files to delete.

Now you know how to clean your android phone from junk, how to transfer applications to a memory card (if possible) and how to move files on an android when the internal memory of the android is full. In addition to a memory card, there is another way - storing files on the Internet.

4. Storing files on the Internet

Storing files on the Internet, thanks to various cloud storages, allows you not only to clear the internal memory and free up the memory card, but also to access your files from any device with the Internet through a browser or special applications, you just need to enter your username and password. If you are interested in this topic, we have analyzed it in detail using the example of the most advanced cloud storage- Google Drive article:.

If you are faced with the problem of inability to download new files to the phone, due to the fact that the smartphone's memory is full, then you need to start a small revision and clear the device from unnecessary files... You might think that 16 or 32 GB is a lot, but now you don't know what to do with the accumulated photos and documents on your phone.

Periodically clearing the phone memory can also increase the speed of your smartphone. There are many ways to solve this problem, and we will cover them all.

Phone presets

Of course, if you are looking for a way out of this situation, then you probably have been using your smartphone for several days. But it would be very useful to find out immediately after purchasing the device what exactly needs to be configured for more convenient use and management of saved files.
Each video created, a photo taken, messages sent from instant messengers and by mail, documents received via bluetooth or downloaded from the Internet - all files are sometimes saved in different places, depending on the location special programs nny folders of these same applications.

Therefore, we would recommend to you for further use, create one folder to which you indicate the path to save any downloaded files. Then, regardless of the use of a browser, voice recorder or camera, all files will fall into one folder known to you, and will not be scattered across the phone's memory card.

What files need to be deleted and where to find them?

If your phone has more than 8 GB of internal storage and you want to free up half, then it will take a long time if you do all the operations through your smartphone. It is better to connect the device to your PC - it will be more convenient, faster, and in disputable moments when you do not know the purpose individual files, you can easily find them on the Internet without interrupting the move or delete process. In the meantime, the smartphone is busy with the process of distributing and deleting unnecessary files, do not forget to play your favorites.

An important point, it is advisable to change only those files whose role you know. In order not to create malfunctions in the system. In addition, you should pay attention to the following folders:

• bluetooth
• download
• media
• Movies
• Music
• Video
• Sounds

And on all media files that could appear in the process of using various editors, instant messengers, maps and other applications.

To work without the help of a Computer

For the convenience of working in "manual" mode with files, there is one useful program that can simplify operations with movement - this is ES Explorer. The application interface is designed in such a way that even a beginner can cope with big amount file and folders on your device.

Work through a Computer

There are two ways to work with phone files via your PC. The first is done using a connected cable. Some models require drivers that may not be included in standard set... Or finding them on the net will become a problem.

Another way involves using the AirDroid program, which only needs Internet access on both devices. The application provides access to the internal files of the phone and to the phone book. No cable is required for this, and the work is done through your computer's browser.

Reallocate space

To free up the internal memory of the phone, sometimes you need to transfer some applications to the memory card. But this is not easy to do, without special programs or administrator rights, root-rights, after obtaining which, your warranty will not work and there is a chance to "kill" your android, turning it into a piece of iron.

If you have these rights, then you can use the Link2sd application, which allows the owner to move any programs to the memory card. But when you try to do this with standard, pre-installed programs, their work and work with the Android system may be disrupted.

Without device administration rights, a large number of programs cannot be moved to the SD card, since they will be automatically located in the internal memory of the phone. But to work with the rest, Android Assistant can help you - a functional application, with various tools to help you cope with similar placement problems and more.

On the start page select Toolkit / App2sd / Maybe - you are offered a list of programs that can be transferred to an SD card. And in the Program Information section, go to → To SD Memory Card.

Remove accumulated garbage

In cases where you do not particularly follow the installed content or programs downloaded from the Internet, the above operations may not be necessary - it will be enough just to delete unnecessary files and applications that interfere with the installation of new ones.

The Android system attracts various kinds of rubbish, so periodic cleaning is simply necessary, as if it concerns your room, for personal hygiene. While deleting unnecessary files, cache, programs helps the phone to work better and faster.

As in other situations, we cannot do without a helper program. And here, it will be - Clean Master. The first page invites us to analyze all programs and files available in the smartphone, after which you delete them with one touch. This app is also useful for its Advanced Cleaning feature, where you can find everything ever installed programs and the resulting files. But be careful, if you do not want to lose them, just mark the necessary ones and feel free to delete the unnecessary ones. In addition, the program

But before you go headlong to correct this injustice, it is worth finding out why this is happening and how exactly you can clean the system.

Android file system structure

Data-lazy-type = "image" data-src = "http://androidkak.ru/wp-content/uploads/2015/09/faylovaya-sistema-android.png" alt = "(! LANG: File system structure Android" width="200" height="356" srcset="" data-srcset="http://androidkak.ru/wp-content/uploads/2015/09/faylovaya-sistema-android..png 168w" sizes="(max-width: 200px) 100vw, 200px"> !} One thing worth understanding: file system Android is nowhere near as versatile as, say, Windows. If on Windows your programs and media files are in the same space, then on Android each type of file has its own section.

System programs - separately, auxiliary files and music - separately. The first section is called system memory, while the last is called the media section.

Why is this needed? First of all, in order to secure the OS as much as possible. If you combine these sections, it turns out that an ordinary media player can inadvertently delete data important for the operation of another program, "put down" the system or simply hammer it to failure with its files, leaving not even a byte for the necessary system programs.

Moreover, these two sections have different levels access. In the media section, the user and third-party programs can create anything. To section system programs There is nothing for Android except these programs.

Because of this order of things, a rather curious situation sometimes happens: several gigabytes are free in the media section, but the phone stubbornly reports that it cannot install an application of a couple of tens of megabytes in size. This is because the section for third-party programs already packed to the end.

In such cases, there is nothing left but to try to clear the system memory in the hope that it will be possible to free these megabytes.

You can view the amount of free system memory in the settings, in the "Memory" section. The first scale shows exactly this value. In addition, it is worth considering that the system requires leaving a certain amount free - from 50 to 600 megabytes, depending on the Android device model and OS version.

Cleaning system memory without superuser rights

If you did not open root access on your smartphone, then your options for cleaning the system partition will be seriously limited. On the other hand, the device warranty will remain intact. Is it worth it? You decide.

If you want to clear the system memory, do the following:

• Go to "Settings".
• Go to the "Applications" section.
• Then go to the "Third Party" tab.
• Press the "Menu" button (three vertical dots in the upper right corner of the screen).
• Select to sort by size.

If there is something among them that you do not use, then click on it and select "Delete". If the button is unavailable, then the application is systemic and cannot be deleted without superuser rights.

Then select "Uninstall updates", this way you will free up at least a little space. It is also advisable to disable the program by clicking on the corresponding button. But this should be done carefully and only with applications like Facebook that are not part of the system.

The above method does not take into account the fact that Android calculates the size of the application on the entire internal memory. If it occupies 1.2 GB on the internal memory card and only 40 MB on the system partition, it will still show up as 1.2 GB.

If you have already carried out such an optimization and there is still little space, you have little choice: get superuser rights or try to transfer applications to a memory card. The latter will only work if your system is version 4.0.4 or lower, so the chance is slim. But if you are indeed a user of a device that is at least three years old, then next to the "Delete" button you will have a button "Transfer to SD-card / USB-drive". Click on it, and some of the data of this application will leave the system partition and will be transferred to the memory card, freeing up space.

Some Android programs are used only by some third-party applications, so they can be erased even without superuser rights. For example, deleting “ Google services Play "allows you to free up to 150 MB in the system partition, closing instead the possibility of direct synchronization between devices. If you are not using programs like Pushbullet or MightyText, you can safely delete it. And if suddenly something is needed by some program, she herself will offer to download it again. The second candidate for deletion is Google search, but along with its 40-60 MB you will lose Google now and the command "Ok, Google!"

Cleaning system memory with superuser rights

And although we will talk about unstable solutions a la Xposed App2SD, which, for example, allow you to replace the application section with a memory card, root users still have more opportunities.

Removing preinstalled programs

If your Android already had installed third party applications(Facebook, VKontakte, Odnoklassniki, MTS Assistant), then most likely you cannot delete them without superuser rights. This is quite a shame, since they often have a sizeable size of 40-160 MB.

The solution is the Titanium Backup program, which allows you not only to make a complete backup of all your applications with their settings, but also to clear the closed system partition from such garbage. To do this, simply select the desired application on the second tab of the program and click "Remove".

Mounting SD card as internal memory

As mentioned above, 1.5 GB of a game does not always go completely into the system partition. But for those who have a couple of gigabytes of internal memory, this does not make it easier.

Jpg "alt =" (! LANG: Folder Mount program" width="150" height="119"> !} The solution is the FolderMount program, which allows you to transfer cache files (this is what these one and a half gigabytes are called) to a memory card, leaving a shortcut instead. In this case, the system will still assume that the files are in the old location, which leads to funny curiosities in the "Memory" settings section: for example, you can see that 8.2 GB out of 3.6 GB is occupied, while another 0.98 of these 3.6 are absolutely free.

If FolderMount cannot create folder on SD card, please do it yourself by anyone file manager and specify in the program. You can also copy the files of the portable program there immediately, deleting them later from the internal memory - this is more reliable. And if you see a message that mounting is not possible, enable "Autostart" or "Mount at startup" in the settings and restart your smartphone.

Other section extension methods

However, most of them are extremely dangerous in the hands of inexperienced users, only suitable for a specific model / manufacturer, or require a high level of technical skills.
