How to access the Android system memory and the data folder

Modern smartphone users often face restricted access to certain sections of the file system. This issue became especially acute with the release of version Android 11 and subsequent releases, when Google tightened its security policy. Now the standard file manager does not allow you to just go to the root directory or see the contents of the folder /Android/data. This is done to protect user data from malware, but creates difficulties for those who need complete control over the device.

In this article we will look at all the legal and technical ways to circumvent these restrictions. You'll learn how to use USB debugging capabilities, special explorer apps, and even methods to gain root privileges. Understanding the structure of the file system is the first step towards deep customization and optimization of your gadget, so it’s worth understanding the details.

However, before starting any manipulations, it is important to be aware of the risks. Tampering with system partitions can lead to operating system instability or data loss. We will look at methods from the safest to the most radical so that you can choose the appropriate option for your tasks.

Why access to system files is limited in new versions of Android

Starting with the eleventh version of the mobile operating system, Google has introduced an isolated storage mechanism (Scoped Storage). This technology has fundamentally changed the way applications interact with files. Previously, any app could request permission to read the entire drive and gain access to all directories. Now, each application sees only its own files and common media directories, such as “Downloads” or “Images”.

This measure was taken for a reason. Data isolation it prevents a situation where one malicious application scans the cache of another service, stealing logins, passwords or configuration files. The folder /Android/data often stores cached game data, offline maps of navigators and temporary messenger files. Direct access to them without restrictions would open a loophole for attackers.

⚠️ Attention: An attempt to forcefully change access rights to system files without understanding the structure of the Linux kernel can lead to “bricking” the device. The system may stop booting if you delete a critical configuration file.

In addition, restricting access protects the integrity of the system itself. Accidentally deleting a library or changing the configuration on the root partition may cause cyclic reboots or errors in the operation of basic services. Therefore, the standard Explorer interface deliberately hides these sections from the eyes of the average user.

Using built-in tools and special explorers

Despite the restrictions, there are ways to view the contents of protected folders without obtaining root access. In Android 11 and above, the standard file manager hides the folder data, but it can still be accessed through the system interface if you know the correct path. This method does not require connecting to a computer or installing complex software.

To use this trick, you will need any file manager that supports working with system documents, for example Files by Google or “My Files” from Samsung. You need to go to the following path:

Internal storage → Android → data

When you try to log in, the system will display a warning that changing files in this folder may lead to errors in the applications. You will need to confirm the action by clicking the “Allow” or “Grant Access” button. After this, you can view the content, copy files from there, or delete the cache of specific apps.

However, this method has its drawbacks. You will not be able to move files inside this directory from other places, and you will not gain access to the root partition of the system /system or /root. For deeper operations, specialized tools will be required.

For those who need more options, there are advanced file managers such as Solid Explorer or CX File Explorer. These applications are able to request special permissions through the system framework SAF (Storage Access Framework). They provide a more convenient interface for working with archives and network drives, while remaining within Google's security rules.

Connecting via a computer and USB debugging (ADB)

The most powerful tool for managing a file system without root access is the debugging interface ADB (Android Debug Bridge). It allows the computer to issue low-level commands to the smartphone. With it, you can copy files from protected sections, install applications, and even change system settings.

To get started, you need to activate developer mode. Go to Settings → About phone and quickly click 7 times on the “Build number” item. After this, a new section “For Developers” will appear in the settings menu. In it you need to turn on the “USB Debugging” toggle switch.

• 🔌 Connect your smartphone to the PC using a high-quality USB cable.
• 💻 Install ADB drivers on your computer (included in Platform Tools).
• 📱 Confirm debugging permission in the pop-up window on your phone screen.
• ⌨️ Open the command prompt on your PC and enter the command to test the connection.

After a successful connection, you can use the commands to navigate. For example, the command adb shell opens the device terminal, and adb pull /path/to/file copies the file to the computer. This is an ideal way to backup your data before risky operations.

ADB command	Description of action	Requires Root
adb devices	Shows a list of connected devices	No
adb shell	Starts a command shell on the phone	No
adb pull /sdcard/file.txt	Copies a file from the phone to the PC	No
adb root	Restarts the daemon with rights superuser	Yes (on eng-firmware)

It is worth noting that without root access via ADB, you still will not be able to read the contents of folders of other applications in the section /data/data. Access will be limited to your user area only. However, for most cleaning and backup tasks, this is enough.

What to do if the computer does not see the phone?

Make sure that the “File Transfer” (MTP) mode is selected in the USB connection settings and not “Charge Only”. Also try replacing the cable or USB port.

Obtaining root access for full access

If you need absolute control over the device, including the ability to delete system applications and edit files in the partition /system, you cannot do without obtaining superuser (Root) rights. This process is called rooting and removes all software restrictions imposed by the manufacturer.

The most popular modern method is using a utility Magisk. It allows you to gain root access by modifying the boot image of the system, while passing the Google Pay security check (in most cases). First, you will need to unlock the device's bootloader, which often results in a complete data reset.

⚠️ Attention: Unlocking the bootloader and obtaining root access will void the device's warranty. In addition, some banking applications and games with anti-cheat may refuse to work on a rooted smartphone.

After installing Magisk, you will be able to use file managers with root support, such as Root Explorer or Mixplorer. They allow you to mount partitions in read-write mode, change file access rights (chmod/chown) and remove pre-installed garbage (bloatware).

It is important to understand that rooting is an irreversible change in the structure of the software in some aspects. Errors when editing system files may require flashing the device via Recovery or Fastboot mode. Therefore, before any action, create a backup through custom recovery, for example TWRP.

Alternative methods through Recovery mode

There is another way to access the file system, which does not require loading the main operating system. This is using Recovery Mode. Standard recovery has limited functionality, but custom versions, such as TWRP or OrangeFox, provide a full-fledged file manager with root access.

To get into this mode, you usually need to turn off the phone and hold down the button combination (often Volume Up + Power). In the recovery menu, you can connect your phone to your PC and see it as a drive. In this state, Android restrictions do not apply and you can copy, delete or move any files.

This method is especially useful if the system does not boot ("bootloop") and you need to save important data before resetting the settings. You can copy the folder /data/media to your computer, saving photos and documents, even if the phone itself does not turn on.

However, installing custom recovery also requires an unlocked bootloader. If your phone is from a carrier or has a MediaTek processor with a locked bootloader, this method may not be available without complex workarounds.

Frequently asked questions (FAQ)

Is it safe to delete files from the Android/data folder?

You can delete files from this folder, but with caution. This is an application cache: maps, temporary game files, autosaves. Deleting will free up space, but the application will download the data again the next time you launch it, which can take time and bandwidth. Do not delete files if you do not know what they are responsible for.

Is it possible to access the system memory without a computer?

Yes, with the help of special file managers (for example, MiXplorer or Solid Explorer), which can request access through the SAF system framework. However, access will be limited only to the user section, deep system files without Root will remain closed.

Why did access to Obb disappear after the Android 13 update?

Google continued to tighten its Scoped Storage policy. In Android 13, folder access Android/Obb is also limited for third-party applications. You can only gain access through the system explorer with confirmation or through ADB with developer rights.

Will the phone reset the warranty when you enable USB debugging?

No, enabling USB debugging itself does not void the warranty. This is a standard feature for developers. You lose the warranty only when you unlock the bootloader and obtain root access, which is a deep intervention in the software.

How to restore access to folders after resetting the settings?

After resetting the settings, all restrictions return to the factory ones. You will have to re-allow access to file managers through the system confirmation window the first time you try to enter the folder Android.
