First, delete the folders and get acquainted with the article.

Android folders - structure

The list of folders may vary depending on the Android version. Some programs can create various directories in memory, for example, instant messengers. However, the list of folders on all versions of Android will be the same, so you need to know what is stored in them.

• Cache – a folder with timely update files. If you do not intend to change the system, you can delete it.
• data/app - installation files of all third-party programs. If you don’t hate them, you can see.
• data/data - setting up, saving and other service information, necessary additions. If you are not interested in installed programs, delete the directory.
• data/clipboard – buffer for exchanging data with the remaining screenshots. It is not recommended to delete.
• data/dalvik-cache – cache memory area for the Java virtual machine, which allows the phone to run APK files. It is necessary to clean files regularly, otherwise they cannot be deleted. (read)

The Documents folder stores a variety of documents. If you don't want to save this place, please calmly delete the catalogue. There are also Bluetooth directories, in which the files are transferred, which are accepted for this drone-free technology.

Father DCIM saves photographs taken on camera. If there are no required photographs, you can send the catalog without fear. There are no folders on the Android robot: Images, Pictures, Musi, Audio, etc.

Folders that cannot be deleted

In Android there are folders that absolutely cannot be deleted, and the system will not function correctly without them. Remember this name:

• efs - information about IMEI, Mac, Bluetooth and Wi-Fi.
• etc - configuration files that are used to modify the system and processes of various programs.
• lib - libraries, necessary programs and modules.
• mnt - image of the systems to be installed.
• proc - key information about the installed system.
• sbin - concatenated files of all programs that participate in the system.
• sys – current system configuration.

Every time you cannot delete the system folder with all the directories contained in it. System is the backbone of the system, so as soon as you delete this data, you will flash the phone again.

Ways to see

To delete system folders, you need super user rights – root. If you don’t have them, then you definitely won’t be able to hack Android. Obviously, you need to be extremely careful - deleting important system files will result in you having to flash the device again.

Once you have figured out which folders can be deleted painlessly, then proceed to clear the memory using additional standard functions:

1. Open the Android main menu and launch the file browser (file manager).
2. , Yaku can be seen. Press it on it and rub it with your finger.
3. When the menu appears, select "Visibility".

There is a manager option with support for multiple selection. The delete button is located in this case for the right-handed animal next to the cat icon.

The standard file manager does not display all Android files and folders. To properly clear the device’s memory, use ES Explorer or another file manager.

1. Launch ES Explorer.
2. Choose what to clean - Internal Storage or Memory Card.
3. Place your finger on your dad if you need to remove it. Once done, you will begin to see other files and folders.
4. After selecting all the deleted items, click the “Delete” button in the bottom menu.

You don’t have to bother with file managers on Android, but simply connect your phone to the computer, selecting the media device mode, in which you can view and change memory.

One of the most popular operating systems today is Android. It is installed on millions of mobile devices. The system contains a set of folders and files to support the robot. Have you ever wondered what the skin daddy streams? The deeds are trying to get through the great vagus, and the hand is so eager to see them out. First of all, it’s important to be aware of what your folder stands for, as well as how important the operating system is. We also know how to delete an unnecessary folder.

Main key directories in the Android operating system

The Pershochergova Store in front of the collections – you don’t need to know what to put in the directory, and even where to lie, you can delete them. If you accidentally delete important files, you can ruin the work of any programs, or cause the entire operating system to become even more useless.

Please note that the list of folders may vary depending on the device version of Android. Also, specific programs can create folders in the memory of an Android phone. Let's take a look at what directories are in Android.

Cache is a folder for saving timely files. She may have an updated system. If you do not intend to update to the latest version of Android, you do not need the update file. You can delete this folder, but in some cases you may need to browse to it.

Data is one of the largest catalogs, which, as you can guess from the name, contains a variety of data. This includes cloud account data, information about saving passwords, Wi-Fi access points, etc. So how does this folder contain anonymous information, let’s look at its subdirectories:

1. App – directory in which installation files of various programs are located. You can delete them if you don’t need all the programs on your phone;
2. Data – includes setting up, saving and other service information necessary for the operation of specific add-ons. If there is no data in the appendix that is important for you, it can be deleted;
3. Clipboard is a special data exchange buffer that also contains the remaining screenshots. You can view the folder, but it is not recommended;
4. Dalvik-cache is a cache memory area for programs called Davlink. This program is a Java virtual machine that allows the phone to run apk files of the program. To speed up the process as much as possible, files are created in cache memory. It is recommended to clean it regularly, otherwise you will not be able to remove the dalvik-cache.

The efs folder contains information about the phone's serial number (IMEI), MAC address, Bluetooth and Wi-Fi. This directory cannot be deleted. Moreover, it is recommended to make a backup of all the folders, leaving some of your deleted ones before losing the unique number of your smartphone.

The etc directory contains configuration files that are important for the installation of the OS, the processes of various programs, for example, the designated place for GPS deployment. This is one of the system directories that cannot be removed.

The lib directory contains various libraries necessary for the correct operation of program functions and modules. This folder also contains files to ensure that the drivers work. It’s impossible to delete it.

The mnt directory – contains images of systems to be mounted. Here you can see uninstalled sections of the installed memory card, internal memory or other virtual devices. It is obviously not possible to view this catalogue.

The proc folder – it contains all the key information about the installed Android OS: information about the kernel, configuration parameters and hardware. All external files and folders are virtual, in which case zero bytes are important. The system automatically creates them if the customer denies access to them. It is not possible to view this folder with koristuvach rights.

The sbin directory is one of the key folders needed by the phone. It contains files of all programs used to manage the system. Obviously, it’s impossible to see it.

The sys directory contains the current system configuration. This is a dynamic catalogue. Everyone's information is constantly changing. You can't change the folder.

The system section is the “backbone” of the entire operating system, which is why all the files are stored, without which the Android robot is impossible. The System directory (as well as any other internal directories) cannot be deleted. For information, let's take a look at the report in addition to this catalogue:

1. App – system tapes, standard programs (calendar, notebook, SMS) are in this folder.
2. Bin includes the files that have been compiled and sent;
3. Build.prop adjusts the amount of adjustment on the phone, for example, how much the sensor is affected after pressing, depending on the thickness of the screen;
4. Fonts – information about all stock fonts that are supported on the phone.
5. Framework – everything needed for the interface, closing icons, curtains and other graphic elements;
6. Lib – library of add-ons;
7. Media – all standard melodies and sounds (alarm clock, SMS notifications, call melodies);
8. Tts includes mobile packages.

Documents – a folder that can contain various documents, including files in .doc and .pdf formats. If you don't have to save the folder, it can be deleted.

Bluetooth – place all files received by the device via Bluetooth. Since there are no important data, you can see them without any problems. It may be stored not only in the internal memory, but also on the SD card.

DCIM is a special directory for saving photographs taken with the camera of your smartphone. As a rule, it includes a Camera section, in which all photos are displayed. If the photos you need are not on your phone, you can delete them. You can also delete sections such as Pictures, Images, Audio, Music (including important files in the middle).

Methods of viewing

How can I view a specific folder? The first way is to quickly use standard functions. For whom is it necessary:

Few people know how to clear the cache on Android. It dawned on me that even though I was holding a new smartphone in my hands, I was completely satisfied. Everything works smoothly, the interface works smoothly and does not crash at all, and the add-ons that hang up are often intermittent. However, as many months go by (and sometimes even more), our device begins to “stumble”, it would seem that rightfully so – programs take longer to run, animations lose too much smoothness, and The scene at the internal junction begins to become increasingly clear.

There may be a lot of reasons for such a thing, but first of all, what you can do to speed up the work of your Android device is to clean up some unnecessary files that accumulate during the life of your apps: this may be data about the compilation, outdated files, photo thumbnails, browser cache or VK, cookies and mass of other ballast, which is our hostility towards working with a gadget. Such axis "smatter" files are designated by the term "cache" (from the English "cache" - storage), and the procedure for deleting them is similar to clearing the cache.

70% of excess files are not needed on the computer, nor on the device, and will negatively affect the operation of the smartphone, most of the time when running programs and installing the system. You can safely see them and not be afraid of the inheritance.

However, the cache can store important data, for example, saving your audio recordings, photos and passwords. Therefore, you need to approach the memory clearing procedure wisely. You should learn to separate those files that may be useful for the normal functioning of the device, and those that can be safely cleaned without fear of losing important information.

See cache

The Android operating system can cache three different types of files:

• The first type of cache is non-systemic. These files were created by programs of the user, imported from the Play Market or other devices. If a personal program is installed on the device, such a cache can reach the size of a computer and then definitely cannot be done without cleaning;
• Another type of redundant files is system files. As a rule, they can be removed without shame. The Android operating system will still not allow us to erase those that are needed for normal work;
• And, let’s find out, the third type of cache is Dalvik. Generated by the system so that the most frequently abused programs are launched faster. Let's not go into the delicate robotic middle. Moreover, the dalvik-cache cleanup is not available to the average user, since it requires removing root rights and installing a custom recovery.

Basic methods of cleansing

Having learned that we now need to clear the cache of our smartphone, let’s move on to the procedure. In most cases, it is possible to clean smudge files without installing additional software. Suppliers of current Android shells, which are supplied, for example, with devices from Samsung Galaxy, Asus or Lenovo, will provide their products with add-ons that allow them to optimize the device in the most comprehensive manner.

There are more ways to clear the cache that may be needed, for example, if the device does not stick or is always re-invented. Let's take a closer look at which files can be changed, and which ones can be deleted.

Purification through customization

You can immediately access all the files that have accumulated on the device by simply going to the settings menu and pressing three buttons.

Robimo takes:

1. On the desktop or in the curtain, you will find the adjustment gear and go to the “Convergence” section (or “Memory” - the names can be changed according to the firmware or the device will be installed).

1. Embossed on a row “Cleansing cache”. Don’t hesitate, we confirm the procedure and are happy to release an additional 1-2 GB of expensive memory for the device.

That's it! The phone was safely cleared and it didn’t take us 2 hours. It’s easy to work out, using this method does not transfer the differentiation of files that can be seen - Android to see those that are important for the need, and we are deprived of knowing that this list cannot be included, for example, our dear music from VKontakte, caching we've been doing this long and lightly. Ale, if you don’t have anything special to spend, you can try it.

How to clean only in one program

It happens that the gadget works flawlessly, and one axis or a number of add-ons are constantly working: then, for example, “Odnoklassniki” crashes when you try to send a notification or the game is “farmed” on the singing level - the situation It is broad and even prosaic.

In order to correct it, you don’t have to reinstall the add-on again – just clear your cache. So, you may have to enter your password and login again, but there’s nothing wrong with that. As a result, we receive a fresh and adequate supply of food.

So, to clear the cache of any program (for example, Instagram), we need:

1. Go to Settings and select the item “Storm of programs” or “All programs” - the name, again, can be changed depending on the version of “Android”.

1. Find the program on the list that keeps us safe, and click on it. In some versions of the Android OS, programs are divided into groups: “system” and “core”. It will be easy to find out, since there are a lot of programs installed on the device.

1. Click on the item “Cleansing data”. Embossed on the new one and fits well. The memory will take just a few seconds to clear, then we can check the robot's programs. Once you've done everything, you'll never get any more treasures.

Clear cache for additional third-party programs

The methods discussed earlier were, of course, valid - you can check them out if you follow our instructions step by step. However, you can’t call them too manual - manually going through settings, selecting menu items, and also risking wasting important data - this is not the best job. It’s much easier to run a comprehensive program on your smartphone to clear the cache, so that you can quickly and easily delete only those that are not needed.

In this article, we would like to demonstrate the operation of two such programs - in our modest author’s assessment, they are the most user-friendly for corn crops and, at the same time, the most functional. This program is Clean Master and App Cache Cleaner. Let's take a closer look and demonstrate its robot with additional screenshots.

Clean Master add-on

It’s a very handy utility, as millions of customers have already appreciated - it itself, of course, works for cleaning Xiaomi phones.

To evaluate the capabilities of this program on your own and understand how it can help clear the cache, we need:

1. Find and download the program through the Play Market.

1. Open it and look at the list of functions that the program provides - on the main page. It's possible that, after clearing your cache, you'll need more from this list.

1. We press the “Smitt” key, decorated with the Smitt cat icon, and the program begins to determine how much of the data that is saved on our device can be safely deleted (there will be a difference in system connections you, cookies, sketches of photographs and other things).

1. Press the “Clear Smudges” button and add an impressive animation to accompany the process. Ready!

App Cache Cleaner

Another one, in our opinion, is a great program for clearing the cache on Android. These functions are very similar to those we looked at earlier, although the minor differences are still the main feature in the interface.

In addition, the utility can transfer programs from internal memory to an SD card. This is a very useful function, since the size of the device in your device does not spoil its dimensions - Clean Master does not implement such a function. So, in order:

1. For starters, just download the add-on from the Play Market. Then open it by clicking on the desktop and become familiar with the functions.

1. We are labeled “Swidka cleansing” – it is embossed on the cat icon for smudge and is very similar to those that were on the front butt.

1. Everything is absolutely the same: if you put a file you need into the list of what you have seen, then simply uncheck it and the program will not read it. Ready!

Reset factory settings (Hard Reset)

If you have already tried all the methods, and the phone is still acting up or performing even worse, we may be glad to release all the data. The method is initially radical, but invariably effective - the phone remains as good as new and again gives us the fluidity of work. All the problems that you have accumulated without turbo over many months of using the device will no longer bother you.

You can get your phone up and running before the weekend in two ways:

• through the add-on “Nalashtuvannya”;
• through the update menu (or “recovery”).

These methods are implemented in different ways in the devices of different detectors. Information about how you can access the update menu on your smartphone can be found at.

In order to restore the device to factory default using the operating system, please do the following:

1. Let’s go to settings and find the “Update and discount” parameter. On smartphones running MIUI 9, this item is located in the “System and Devices” section of the list of advanced settings.

1. “Clearing data” will be displayed and a number of boxes will be checked, as a result of which all files on our device will be completely deleted – we suspect that it is not easy to guess about the need for a backup copy.

1. Ready! Get your new device!

The programs installed on our device continuously save excess files of their life. We don’t need most of them and can safely remove them - to make the robot easier to work with, to improve memory and to speed up the device a little. Clearing the cache is the first thing you need to do to restore the normal functionality of your mobile phone. You can earn money through customization or through other programs. If the situation with productivity is even deplorable, you can go as far as factory adjustments.

Video instructions

First, finish and drink, watch this video.

You already know what the recovery menu is. We remember that there is a special mode for smartphones based on Android, which allows you to perform various activities with the smartphone, including downloading settings or installing programs. One of the items in the recovery menu may be called Dalvik Cache. What does this mean?

Axis one of the applications recovery menu, this item is called something else - Wipe Dalvik/ART Cache:

The essence of the name of the menu item does not change.

Dalvik cache is an intermediate buffer with easy access to information contained in it that may be requested by the Dalvik virtual machine. Speaking more simply, this is an hour-long compilation of program code.

What does Wipe Dalvik Cache mean? This means that you need to clear the Dalvik cache so that additional code files can take up space in the smartphone’s memory. When there is no need to remove the files, the debris will be created by the system if necessary. We highly recommend Dalvik Cache if you have any problems with your smartphone.

To create a Dalvik Cache wipe in a TWRP cover, you need to open “Cleanse”.

Then press “Vibirka cleansing”.

Check the box opposite Dalvik/ART Cache and swipe.

Now you know what Dalvik Cache means.

Richly decided to confirm that before installation custom ROM, for example, it is necessary to earn wipe systems, although this is also the main idea. How about this situation? There is only one answer: the first option is correct. Why so? Let's try to get married.

Wipe Directions to clear parts of your device’s memory. The operation must be carried out both before the loss of special data and the loss of attractive additional benefits. Systematic programs produce the cob mill. Come out now wipe I turn your device over to where you bought it from.

There are a number of different wipes and a short description of them:

Wipe data/Factory reset: In this case, all your special data will be removed, and the system will have a cob appearance.

Wipe Cache Partition: What's the point of bringing the cache to the surface. Which method has special properties not to be lost.

Wipe Dalvik Cache: all your programs are located in the Dalvik cache directory tree, wipe sticks around itself, in which case the tributes are deprived of the unfinished ones.

Yakiy wipe Who should get stuck? Why do you have it?

When you install a new ROM don't work wipe, then one loses a lot of “smell” from the old system, which leads to the unstable operation of the new one. You will eliminate a bunch of problems, problems and other problems. For these reasons wipe forever necessary.

Let's now take a look at what kind of wipe you have.

When you install a new one custom ROM, just before they vikorized the stock firmware, varto zastosovat the first version - Wipe Data It is also necessary when migrating from one version to another, for example.

As soon as we talk about minor updates, for example, you go to CyanogonMod 9.0 before CyanogenMod 9.1 or you install it, then it is necessary to stagnate" Wipe Cache Partition"і" Wipe Dalvik Cache".

On tsyomu, vlasna, that's it. Now you know what wipe helps solve a lot of problems associated with custom ROM. Once you install a batch of treats in the robotic wine system, you can easily put them in. Well wipe does not help, you need to quickly select the "" option in recovery mode. We hope that now we will ask about the topic of work wipe no matter what, you are not to blame.
