How to find and open hidden files on Android: complete guide

Hidden files on Android are not just system data that developers have hidden from the user. Often these are important configuration documents, application caches, backups, or even user-forgotten media files that have been mistakenly assigned the “hidden” attribute. For example, photos from instant messengers are often saved in a folder .thumbnails, and the settings of some games are stored in directories with a dot at the beginning of the name.

Many users are faced with the need to access such files - be it to free up memory, recover deleted data, or manually configure applications. However, the standard Android Explorer default does not show hidden elements. In this article we will analyze all the current ways to display them: from built-in tools to using ADB and specialized file managers.

⚠️ Attention: changing or deleting system hidden files (for example, in folders /system or /data) may cause the device to malfunction. Backing up data before any manipulation is mandatory.

1. Enabling the display of hidden files in standard explorer

On most modern devices (starting from Android 6.0 Marshmallow), the built-in file manager can show hidden items, but this option is often hidden in the depths of the settings. The algorithm of actions depends on the manufacturer and version of the shell:

On pure Android (Pixel, Nexus, Android One) the path is as follows:

1. Open the application Files (Files by Google).
2. Tap on the three horizontal lines (menu) in the upper left corner.
3. Select Settings → Show hidden files.
4. Activate the switch.

For shell Samsung One UI, Xiaomi MIUI or Huawei EMUI the process is different:

• 📱 Samsung: My file → ⋮ (menu) → Settings → Show hidden system files.
• 📱 Xiaomi/Redmi/Poco: Explorer → ⚙️ (settings) → Advanced → Show hidden files.
• 📱 Huawei/Honor: Files → Categories → ⋮ (menu) → Show hidden files.

If your Explorer does not have this option, it means that the manufacturer has limited the functionality. In this case, you will have to use third-party solutions (see the next section).

⚠️ Attention: on some devices with Android 13+ display of system hidden files (for example, in /data) may be blocked even after enabling the option. This is due to the security policy Google.

2. Third-party file managers with support for hidden files

If the built-in explorer fails, third-party applications come to the rescue. They not only show hidden files, but also often offer additional features: cloud storage, FTP server, memory analysis. Here are the top 3 proven solutions:

Application	Features	Cons	Link (Play Market)
Solid Explorer	Two-panel interface Support FTP/WebDAV Built-in archiver	Paid version after 14 days	com.lonelycatgames.Xplore
FX File Explorer	Open source code Supports root access Built-in text editor	Advertising in the free version	nextapp.fx
MiXplorer	Work without the Internet SMB/NAS support Dark theme and customization	Complicated interface for beginners	com.mixplorer

To enable display hidden files in these applications are usually enough:

1. Launch the manager.
2. Go to settings (icon ⚙️ or three dots).
3. Find section View or Display.
4. Activate option Show hidden files.

MiXplorer is distinguished by the fact that it allows you to configure display filters: for example, show only files with the extension .nomedia or ignore the application cache. This is useful if you need specific types of hidden data.

3. Using ADB to Access Hidden Files

Android Debug Bridge (ADB) is a debugging tool that allows you to manage your device through the command line. With its help, you can even access those hidden files that file managers do not show. The method is suitable for experienced users.

You will need:

• 🖥️ A computer with ADB drivers installed.
• 📱 Enabled USB debugging on the phone (Settings → About phone → Build number — tap 7 times, then return to Settings → System → For developers).
• 🔌 USB cable (preferably original).

Step-by-step guide:

1. Connect your phone to the PC and confirm trust in the computer on the device screen.
2. Open the command line (Windows) or terminal (macOS/Linux) and enter:

adb devices

If the device is shown in the list, run:

adb shell ls -la /sdcard/

This command will show all files (including hidden ones) in the root folder of the internal memory. To copy a hidden file to your computer, use:

adb pull /sdcard/.file_number C:\path\on\PC

Critical: ADB commands with root access (for example adb root) can break the system. Do not use them without a clear understanding of the consequences.

What to do if ADB does not see. device?

1. Check if the drivers are installed (for Windows, download them from the phone manufacturer's website).

2. Try a different USB cable or port.

3. Restart the phone and PC.

4. Enable the "Cancel" option in the developer settings. USB debugging authorization" and reconnect the device.

4. Finding hidden files through Total Commander

Total Commander is a legendary file manager that also exists for Android. Its main advantage is the flexibility of settings and support for plug-ins. To find hidden files:

1. Install Total Commander from Play Market.
2. Launch the application and tap on the icon ⋮ (menu) in the upper right corner.
3. Select Settings → Display.
4. Activate the options:
   • Show hidden files
   • Show system files (optional)

Return to the root folder (/) and refresh the view (button ↻).

In Total Commander hidden files are displayed translucent, and system files with an exclamation mark. This helps to quickly distinguish them from regular data. In addition, there is a built-in search by mask: for example, enter .* into the search bar to find all hidden items.

Example path to often hidden folders:

• 📁 /sdcard/.thumbnails — thumbnails of images and videos.
• 📁 /sdcard/Android/data — application data (often hidden from the user).
• 📁 /sdcard/.nomedia — files excluded from media scanner.

5. How to hide or show files manually

If you need not just to view, but control the visibility of files, this can be done. without third-party applications. In Android, the hidden status is determined by a dot at the beginning of the name (for example, .myfolderThis is how it works:

To hide a file/folder:

1. Connect your phone to your PC or use a file manager.
2. Rename the file by adding a dot to the beginning of the name. For example, photos → .photos.
3. Refresh the folder view (click F5 or restart Explorer).

To make the file visible:

1. Turn on display of hidden files (see section 1 or 2).
2. Find a file with a dot at the beginning.
3. Rename it by removing the dot.

Important: some system applications (for example, gallery) ignore files with the extension .nomedia. If you want the photos not to be displayed in the gallery, but remain available in Explorer, create an empty file in the folder with images. Renaming system hidden files (for example, in a folder .nomedia.

⚠️ Attention: renaming system hidden files (for example, in the folder /system) without root access can lead to errors in Android. Always check the path before changing.

6. Restoring hidden files after a failure

Sometimes hidden files “disappear” not through the user’s fault, but due to file system failures, viruses, or incorrect device shutdown. In such cases, it will help:

• 🔍 Check for viruses: use Malwarebytes or Dr.Web Lightto exclude the action of malware that could hide files.
• 🛠️ Recovery via DiskDigger: the application scans the memory and finds deleted or hidden data (works without root, but with root is more effective).
• 💾 Checking the file system: connect the phone to the PC and run chkdsk (Windows) or fsck (Linux/macOS) to fix errors.

If the files were hidden by a virus, the following sequence of actions often helps:

1. Install Total Commander and enable display of hidden files.
2. Go to folder /sdcard/ and find files with suspicious names (for example, .trash-123 or .vault).
3. Check their properties: if the modification date coincides with the time the files “disappeared”, rename the folder by removing the dot.
4. Reboot device.

To recover media files (photos, videos) from hidden folders, Recuva (on a PC) or PhotoRec (for advanced users) are suitable. These tools scan memory at a low level and can find files even if they have been deleted or hidden.

7. Common errors and how to avoid them

Working with hidden files is fraught, which can lead to data loss or system failures. prevention:

Error	Consequences	How to avoid
Deleting files from /system or /data	Android loading failure, loss of functionality applications	Do not change files in system partitions without a backup copy and root access
Renaming .nomedia in media folders	Photos/videos are duplicated in the gallery, slowing down the media scanner	Use .nomedia only for folders that really need to be excluded
Changing access rights (chmod) without knowledge	Applications lose access to their data, errors when starting	Use commands chmod only according to instructions for specific files
Ignoring backups	Loss of important data in case of failure	Create backups through adb backup or Titanium Backup (root)

One of the most insidious errors - attempt to open binary hidden files (for example, .dex or .so) in a text editor. This can damage the file and crash the application to which it belongs. If you need to view the contents of such a file, use specialized tools like JADX (for APK decompilation) or Ghidra (for analyzing binaries).

Another important point: not all hidden files are safe to delete. For example, the folder .android_secure contains encrypted application data, and .data in the root of the memory are temporary system files. Deleting them may require resetting the settings.

FAQ: Answers to frequently asked questions

Is it possible to see hidden files without root access?

Yes, most hidden files (for example, in /sdcard) are accessible without root. However, system hidden files (in /data or /system) require superuser rights or ADB with the appropriate permissions.

Why, after enabling the option, hidden files are not available? are displayed?

Possible reasons:

• Explorer is not updated (try restarting it).
• The files are really deleted (check via DiskDigger).
• The manufacturer has blocked access (relevant for some devices on Android 12+).

How to hide a folder from a specific application (for example, a gallery)?

Create an empty file in the folder named .nomedia. This will prevent scanning of media files in this directory. To hide from all applications, add a dot at the beginning of the folder name (for example, .my_photos).

Is it possible to restore hidden files after resetting the settings?

If the reset was done through Settings → Reset, then the files in the internal memory (/sdcard) are usually saved, but become inaccessible. Use Total Commander with the display of hidden files enabled to find them. If the reset was performed via Fastboot or Recovery, the data is permanently deleted.

Which hidden files can be safely deleted to free up memory?

You can safely delete:

• Application cache in /sdcard/Android/data/package_name/cache.
• Folder .thumbnails (thumbnails are regenerated automatically).
• Application logs (files with extension .log or .tmp).

Do not delete:

• Files in /system or /data without root.
• Folders with application settings (for example, .whatsapp).
• Files with unknown extensions (for example, .db-shm or .wal).
