The operating system Android has come a long way in evolution, and each new version brings changes to the security and file management architecture. With the release of the eleventh version, known as Red Velvet Cake, Google introduced strict restrictions on access to the root directory of external memory, which radically changed the familiar landscape for users and developers. If previously you could freely move installation files throughout the drive, now the system strictly regulates where exactly you can save data.
Understanding where applications are stored in Android 11is critical not only for freeing up space, but also for creating complete backups. Users often encounter a situation where the file manager stops displaying the usual directories, causing confusion. In fact, the files have not disappeared anywhere, the access rights to them have simply changed, which is part of the concept of Scoped Storage (limited storage).
In this material we will analyze in detail the physical location of installation packages and user data. You will learn the difference between the system partition and internal memory, and also receive working instructions for managing these resources without the need to obtain root access.
Data storage architecture in the new OS version
A fundamental change affected the directory structure on external storage. In previous versions of the system, apps could create folders in the root of the internal memory, which led to chaos and mixing of user files with system caches. Now all application data related to media files and documents must be located in strictly designated containers.
The system divides storage into two logical zones: a private area, accessible only to the application itself, and a public area for shared media files. Private data are stored in a protected section, which is hidden from ordinary file managers without special permissions. This is done to prevent malware from scanning and stealing information from other apps.
⚠️ Warning: Attempts to manually move system files from protected directories may result in installed apps not working. The system automatically blocks the launch of applications whose file integrity has been violated.
For developers, this means the need to rewrite the code for working with files using special access APIs. For the average user, the changes are that when you connect your smartphone to your computer, you see fewer folders than before. This is not a bug, but a planned security feature.
Why did Google introduce such restrictions?
The main reason is to protect user data from spyware applications. Previously, any application with access to memory could read your photos, documents, and the cache of other apps. Now each application is isolated in its own sandbox.
System partition and installation of APK files
When you download an application from the store Google Play or install it manually via an APK file, the bulk of the code is located in the system partition of the device. This partition is usually mounted as read-only for the average user. The path to the executable files looks like /data/app/, but access to it is prohibited without superuser rights.
Optimized files are stored here DEX (Dalvik Executable), which are directly executed by the smartphone processor. This directory also contains libraries .sonecessary for the operation of native application code. You will not be able to see the contents of this folder using conventional file manager tools.
If you use your computer to manage files via the MTP protocol, the system partition will be completely hidden. This prevents accidental removal of critical operating system components. Even if you have root access, you must be careful when editing files in this area.
System application files are located in the protected /data/app partition, which is not viewable through a standard PC connection interface.
To view the contents of the system partition, advanced users use USB debugging. By connecting your device to your PC and activating developer mode, you can access the file system through the command line. This is the only legal way to see how much space the executable files of the apps themselves take up.
User storage and Android folder
The bulk of the data with which the user interacts is now concentrated in the directory /sdcard/Android/. This is where applications save cache, downloaded files, databases and settings. In Android 11 this folder has become the central hub for all I/O operations of third-party apps.
Within this directory there are two key subdirectories that need to be distinguished:
- 📁
data— private data of each specific application is stored here, including settings and temporary files. - 📁
obb— in This folder contains additional resources for heavy games and apps, often occupying several gigabytes. - ⚙️
mediais a new type of folder in Android 11, designed to store media files created by applications.
Previously, applications often created their folders directly in the root of the internal memory, for example, /WhatsApp/ or /Telegram/. Now apps such as instant messengers are required to transfer their data inside /Android/media/ or /Android/data/. This clears the root of the storage from garbage, but complicates the manual search for files.
⚠️ Attention: When deleting an application through system settings, the folder in
/Android/data/may be automatically cleared. If you want to save your game progress or settings, make a backup copy of this folder before uninstalling.
Standard file managers built into the smartphone shell (for example, MIUI or OneUI) can hide the contents of the folder Android by default. To see the files, you will need to provide special permission in the settings of the Explorer application or use third-party software with extended rights.
How to access hidden folders without Root
Many users are wondering how to open access to application data if the standard Explorer shows an empty folder. Google has blocked access to Android 11 Google has blocked access to /Android/data all third-party applications, even if you gave them permission to access all files. However, there are workarounds.
One of the most effective methods is to use a file manager Files by Google or specialized utilities like Material Filesthat can request access through the system SAF (Storage Access Framework). When you first launch such an application, you will be asked to go to system settings and manually confirm access to a specific folder.
An alternative method is to use a computer. When connecting a smartphone via USB, some PCs allow you to (view) the contents of the folder Androidalbeit with restrictions. You can copy files from there, but writing new files may be prohibited by the system.
Use Xiaomi's File Manager or Samsung's My Files app with caution - in recent updates they have also started hiding the contents of the Android folder for increased security.
If you have a critical need to manage files in this directory, consider using ADB (Android Debug Bridge). This is a tool for developers that allows you to give commands to your smartphone from your computer. With it, you can copy, delete and move files to protected areas without obtaining root access.
Memory management and clearing cache
Understanding the storage structure helps to effectively manage free space on your smartphone. Often, users delete applications, but forget about the “tails” in the form of folders with caches or downloaded files in the directory obb. This data can occupy tens of gigabytes, remaining on the device after uninstalling the app itself.
For safe cleaning, it is recommended to use the system’s built-in tools. Go to Settings → Applications, select the desired app and press Storage. Here you will see a clear division into application size, user data size and cache size.
| Data type | Location | Can delete? | Consequences of deletion |
|---|---|---|---|
| APK (Application code) | /data/app/ | No (only through deletion) | The application will stop working |
| User data | /sdcard/Android/data/ | Yes (with caution) | Reset application settings, loss of progress |
| Cache | /sdcard/Android/data/cache/ | Yes | The application will download the data again (slow start) |
| Resources (OBB) | /sdcard/Android/obb/ | Only if the application is uninstalled | The game will not start without these files |
Manually cleaning folders through a file manager is risky, since it is easy to delete unnecessary things. The system automatically deletes the cache when the device runs out of space, but it does not touch user data (game saves, correspondence). Therefore, before selling the phone or resetting the settings, it is important to check the folder /Android/data/ manually.
☑️ Check before clearing memory
Backup and data transfer
Changes in Android 11 complicated the process of creating full backup copies of applications along with their data. Standard Google Drive tools often save only a list of installed apps and some settings, ignoring heavy files from a folder obb or local databases.
A full-fledged backup now requires a more in-depth approach. You can manually copy the contents of folders /Android/data/ and /Android/obb/ to your computer or cloud drive. When restoring to a new device, these folders will need to be returned to the same places before the application is launched for the first time.
Some smartphone manufacturers offer their own cloud backup services, which are better integrated with the system and can bypass some of the limitations of Scoped Storage. However, the reliability of such solutions depends on the policy of the specific vendor.
⚠️ Attention: Interfaces and backup capabilities may vary depending on the manufacturer's shell (MIUI, OneUI, ColorOS). Always check the latest instructions for your specific smartphone model on the official support site.
If you are planning to switch to another smartphone, use the "Quick Setup" function when you initially launch your new device. It allows you to transfer data over a cable or Wi-Fi, automatically respecting the new folder structure and access rights, which is much more reliable than manual copying.
Is it possible to transfer applications to an SD card in Android 11?
Formally, the function exists, but developers must explicitly allow the transfer of their application to external media. Most modern applications (banks, instant messengers) prohibit this for reasons of security and speed.
Frequently asked questions (FAQ)
Why can’t I see the Android folder when I connect my phone to a computer?
In Android 11, access to this folder is limited for third-party applications and the MTP protocol. Try using the file manager on the phone itself to browse, or give special permission to File Explorer on your PC if such an option is available in your OS.
Is it safe to delete files from the /Android/data/ folder?
Deleting files from this folder will reset the settings of the corresponding applications or lose downloaded content (for example, offline maps or levels in games). Delete the contents of only those folders that belong to already deleted apps.
Where are the APK files of installed applications stored?
Installation files are stored in the system partition /data/app/, which is hidden from the user. They can only be extracted using special extractor applications or through ADB commands with developer rights.
How to clear space if the system says “Memory is full” and there are few files?
Most likely, the space is occupied by the application cache or files in the folder /Android/obb/. Go to your storage settings and use the built-in cleanup tool, or manually check the size of large game folders.
Will access to folders return in future versions of Android?
The trend is towards further tightening of security. You shouldn’t expect a complete return to the old file system, so it is recommended to get used to working within the new Scoped Storage architecture.
