The root folder (or root directory) in Android is an analogue of a disk C:\ in Windows: all system files, OS settings and data are stored here applications. But unlike PCs, smartphone manufacturers deliberately hide it from users. Why? Because careless changes in these folders can lead to system crash, loss of warranty or even bricking of the device.
You are here because you are looking for a way to get to the files in /system, /data or /vendor? You may need to edit build.prop, remove bloatware (built-in applications), recover deleted data, or install custom firmware. In this article we will analyze all working methods - from simple (via a standard explorer) to complex (using ADB i TWRP). But first, let's warn you: without root access or an unlocked bootloader, most methods simply will not work.
If you are a beginner, start with the section about safe methods - there we will explain how to view some of the system files without risk. For experienced users, go straight to the pro ADB and Root Explorerpoint. And don't forget: even with root access, editing files in /system can break Android if you don't know the exact paths and permissions.
1. Safe ways: what can be seen without root
Most users mistakenly think that the Android root folder is completely inaccessible without superuser rights. In fact, some of the system directories can be viewed through standard tools - however, only for reading.
The easiest way is to use the built-in file manager (for example, Files by Google or Mi File Manager on Xiaomi). Open it and go to the Device or Internal memorysection. Here you will see folders like DCIM, Downloads or Android โbut this is not the root yet! To get to it:
- ๐ Click on the three dots (menu) โ
Settingsโ enableShow hidden files. - ๐ In the address bar, enter
/(slash) and clickEnterโsome managers will open the root directory. - ๐ฑ On Samsung s One UI try the path
My Files โ Device โ Phone memory โ top folder (model name).
What will you see? Folders like /storage/emulated/0 (your internal memory), /sdcard (symlink to memory) or /mnt. But the real root directory (/) will remain hidden - without root you will not be able to go to /system, /data or /vendor.
If you just need to free up space, don't dig through the system folders! Use built-in cleaning tools in Settings โ Storage or applications like SD Maid (does not require root for basic cache clearing).
2. Access via ADB: for developers and advanced users
Android Debug Bridge (ADB) is an official tool from Google that allows you to manage your device via the command line. With it, you can view files in the root folder, but only if you have an unlocked bootloader or you have root access. Without them, ADB will only give access to a limited set of directories.
To get started, download Platform Tools (included in Android SDK) and enable it on your phone USB debugging (Settings โ About phone โ Build number - tap 7 times, then return to Settings โ System โ For developers). Connect the phone to the PC and run the commands:
adb devicesadb shell
ls /
The first command checks the connection, the second one opens the shell, the third one shows the contents of the root folder. You'll see something like:
```bash
acct
cache
config
d
data
dev
...
system
vendor
```
But there's a catch: Without root, you won't be able to access most folders. For example, the command ls /data will return an error Permission denied. To get around this, you need to:
- ๐ Get root (via Magisk or SuperSU).
- ๐ฑ Unlock bootloader (on most devices this erases data!).
- ๐ฅ๏ธ Use the command
suin ADB to increase rights.
What happens if you run the command rm -rf / in ADB?
This command recursively deletes ALL contents of the root folder, including system files. The device will turn into a โbrickโ and will not turn on. You can restore it only through firmware in EDL mode or using a box (for example, UFi or EasyJTAG).
3. Full access with root access: Root Explorer and analogues
If you have already received root access (for example, through Magisk or KingRoot), then the most convenient way to work with the root folder is specialized file managers. They allow you not only to view, but also to edit system files.
Top 3 applications for working with root:
| Application | Features | Cons | Link |
|---|---|---|---|
| Root Explorer | Classic manager with support for two panels, editing text files, changing permissions (chmod). | Paid (โ300โฝ), outdated interface. | Google Play |
| Solid Explorer | Modern design, support for cloud storage, built-in code editor. | Root functions in the paid version. | Google Play |
| FX File Explorer | Free root access, FTP/SFTP support, built-in archiver. | Advertising in the free version. | Google Play |
How to use? For example, in Root Explorer:
- Open the application and provide root access (a request from Magisk/SuperSU will appear).
- In the top panel, select
/(root folder). - Go to
/system,/dataor/vendorโnow you can edit the files.
Find a backup copy of the original file|Make sure the file permissions (chmod) are enough to save|Check the syntax after editing (for example, in build.prop)|Have the firmware on hand for recovery-->
โ ๏ธ Attention: Changing files in /system can lead to bootloop (loop loading). Always make a backup via TWRP or OrangeFox before editing!
4. Root folder via TWRP: recovery and backups
TeamWin Recovery Project (TWRP) is a custom recovery that allows you not only to flash ZIP files, but also to get full access to the Android file system, including the root folder. Advantage over ADB: you work directly with the device, without connecting to it. PC.
To use TWRP to access the root:
- Install TWRP on your device (look for instructions on official website โeach model has its own method!).
- Boot into recovery: turn off the phone, then hold down
Power + Volume up(the combination may vary). - In the TWRP menu, select
Advanced โ File Manager. - Now you can view and edit any files, including
/systemand/data.
TWRP is especially useful for:
- ๐ Recovering deleted files from
/data(if they have not been overwritten). - ๐ง Bug fixes in
build.proporinit.rcwhich led to bootloop. - ๐๏ธ Creating full backups of the partition
/data(including applications and their data).
โ ๏ธ Attention: In TWRP, the default file system mounted in read-onlymode. To edit files, you need to manually remount the partition in read-write via the TWRP terminal with the command:
mount -o rw,remount /system
5. Important paths in the Android root folder: what is where
Knowing the structure of the root directory will help you find the files you need faster. Here are the key folders and their purpose:
| Path | Purpose | Can I edit without root? |
|---|---|---|
/system |
System applications, libraries, OS kernel. Here are build.prop, framework, app (built-in apps). |
โ No |
/data |
User and application data (settings, cache, databases). Subfolders: /data/app (installed applications), /data/data (their data). |
โ None (except your folder /data/data/your.package) |
/vendor |
Proprietary drivers and manufacturer files (for example, modules for a camera or modem). | โ No |
/storage/emulated/0 |
Your โinternal memoryโ - here are photos, downloads, music. In fact, this is a symlink to /data/media/0. |
โ Yes |
/proc, /sys |
Kernel virtual file systems. (information about processes, hardware). | โ No (read only) |
Examples of useful files for editing:
- ๐
/system/build.propโ here you can change Screen DPI, disable forced encryption, change the device model (to bypass application restrictions). - ๐
/system/etc/hostsโblocking ads or websites at the system level. - ๐
/data/data/com.android.providers.settings/databases/settings.dbโAndroid settings base (you can reset some parameters manually).
Before editing any file in /system or /vendor, be sure to check its original permissions (chmod) with the command ls -l /path/to/file. After the changes, restore them, otherwise the system may not boot!
6. Risks and how to avoid them: 5 rules for working with the root folder
Even experienced users sometimes make mistakes that lead to soft-brick (the device turns on, but does not boot) or hard-brick (full brick). Here's how to minimize the risks:
- Always make a backup. Before making any changes, create a complete copy of the partition
/systemi/datavia TWRP or the command:adb backup -apk -obb -shared -all -f backup.ab - Check permissions. Each file in
/systemhas its ownchmod(for example,644for regular files,755for executable ones, restore them after editing). command:chmod 644 /system/build.prop - Do not delete unknown files. For example, deleting
/system/priv-appwill lead to the loss of all built-in applications (including Settings!). - Use trusted sources. If you download modified files (for example,
build.propto overclock the processor), take them from the forums XDA Developers or 4PDA. - Have Plan B. In case of a brick, prepare firmware for your model and tools for flashing (Fastboot, Odin for Samsung, SP Flash Tool for Mediatek).
โ ๏ธ Attention: On devices with A/B-partitions (most modern Android) changes to /system may not be applied after a reboot. In this case, you need to disable dm-verity (via Magisk or the command fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img).
How to restore a device after unsuccessful editing?
1. Boot into TWRP.
2. Connect your phone to the PC and copy the backup (if you have one) to the memory card.
3. In TWRP, select Restore and restore the partition /system or /data.
4. If there is no backup, flash the stock firmware via fastboot or Odin (for Samsung).
7. folder
Often users try to access the root folder to solve problems for which there are safer ways. Here are some alternatives:
- ๐งน System cleaning: Instead of manually deleting files in
/datause SD Maid (there are root and non-root versions) or the built-in one. cleaning inSettings โ Storage. - ๐ง Changing settings: Many parameters from
build.propcan be changed through applications like BuildProp Editor (requires root, but safer manual editing). - ๐ฑ Removal bloodware: To remove built-in applications, use Debloater (via ADB) or Universal Android Debloater (GUI version for PC).
- ๐ Data recovery: Instead of digging in
/datatry DiskDigger or Recuva (for memory cards).
If your the goal is increase performance, then editing system files rarely gives a noticeable increase. It is much more effective:
- Disable animations in
Settings โ For developers. - Use Greenify to hibernate background applications.
- Flash a custom kernel (for example, FrancoKernel) via TWRP.
Frequently asked questions about the Android root folder
Is it possible to access the root folder without root?
Partially - yes. Through ADB or the file manager you will see some of the system folders (for example, /storage or /sdcard), but you can edit files in /system or /data without root is impossible. The exception is some devices with an unlocked bootloader (for example, Google Pixel), where ADB mode adbd root gives more rights.
What happens if you delete the /system folder?
Device will not turn on. data-i="284">How to copy files from the root folder to a PC?. The folder /system contains critical files for downloading Android. Even if you restore it from a backup, errors in permissions or symlinks may remain. In most cases, a complete flashing will be required.
How to copy files from root folder to PC?
Methods:
- Via ADB:
adb pull /system/build.prop C:\backup\. - Via TWRP: connect the phone to the PC in mode
MTP(in menuMountselectEnable MTP). - Through Root Explorer: select files โ
Copyโ specify the folder on the removable card.
Why does the phone not work after editing build.prop turns on?
Reasons:
- Syntax error in the file (missing semicolon, extra character).
- Incorrect permissions (must be
644). - A critical parameter has been changed (for example,
ro.secure=0on devices with Samsung Knox will trigger the flagKNOX 0x1).
Solution: boot into TWRP, restore the original build.prop from backup or download the stock file for your firmware.
How to find the root folder on Android 13/14? New restrictions
Starting from Android 10, Google has tightened its security policy:
- Scoped Storage: Applications cannot freely read external storage.
- Dynamic partitions:
/systemcan be compressed insuper.img(use lpunpack to unpack). - ADB Limitations: on some devices
adb shelldoes not provide access to/dataeven with root.
To bypass use:
- Magisk with module MagiskHide Props Config for editing
build.prop. - Termux with command
su -c "command_name"to perform actions from root.
If your question is not covered in the FAQ, check the official documentation for your device model on the manufacturer's website or on the forums XDA. Remember: working with the root folder requires an understanding of the Android structure and preparedness for possible consequences. Always start with. backup!
