Modern smartphones series Galaxy from the company Samsung have a complex file structure, which by default hides a lot of system and service data from the user. This is done to protect the operating system Android from accidental deletion of critical components, which can lead to unstable operation of the device or complete loss of data. However, advanced users, developers, or those trying to recover lost information often need to gain access to these hidden directories.
The process of detecting such objects does not necessarily require obtaining root access, although they significantly expand the ability to access the system partition. In a standard situation, it is enough to change the settings of the built-in explorer or use specialized software that can display files with the “hidden” attribute. Understanding where exactly cached data, application logs and temporary files are stored allows you to effectively manage device memory and diagnose performance problems.
In this guide, we will look in detail at all the available methods, from simple interface settings One UI to working with console commands via ADB. You will learn how to find the folder .nomediathat often causes photos to disappear from the gallery, and how to safely interact with system files without violating the manufacturer's warranty.
Standard settings of the My Files file manager
Built-in application My Files (My Files) is the main tool for navigation from smartphone memory Samsung. By default, it is configured to display only user content: photos, music, documents, and downloaded installation packages. To see hidden objects, you need to activate the corresponding switch in the settings menu of the application itself.
Go into the application and click on the three vertical dots in the upper right corner of the screen. In the drop-down menu, select Settings. Scroll down the list of options to the Advanced or Display section. Here you will find the option Show hidden system files. Activating this slider will instantly update the list of directories, making visible folders whose names begin with a dot, for example, .thumbnails or .whatsapp.
It is worth noting that even after enabling this option, some critical system folders in The root of the internal storage may remain unavailable for viewing and editing. This restriction is imposed at the level of user access rights Android, and not at the Explorer interface. To work with such sections, deeper intervention methods will be required, which will be discussed below.
⚠️ Attention: Enabling the display of hidden files does not automatically give you the right to change or delete them. Trying to erase a system file without the appropriate privileges will result in an access error, and in the worst case, a hang of the Explorer application.
If you accidentally deleted an important system file after enabling this option, immediately reboot your device in Safe Mode to prevent loading corrupted modules.
Searching for special .nomedia files and hidden media
One of the most common reasons why users search for hidden files is a problem with displaying photos or music in standard applications Gallery or Music. The culprit of this behavior is often a special marker - file .nomedia. If this empty file is placed in any folder, the media scanner Android ignores the entire contents of this directory and all its subfolders.
To find such a file, use the search function within the application My Files. Enter the exact name .nomediainto the search bar. The system will scan the entire available space and display a list of all matches found. Typically, such files are created automatically by messengers like Telegram or WhatsApp to hide stickers and service images from the general gallery feed.
If you find this file in a folder with personal photos that have disappeared from view, it must be deleted. After uninstallation, it is recommended to clear the application cache Media storage through the smartphone settings in order to force a re-scan of the memory. This will return the disappeared images to the public.

Use third-party file managers with extended rights
Standard Explorer Samsung has limited functionality for working with file attributes. For a more in-depth analysis, it is recommended to install specialized utilities from the store Google Play. The leaders in this category are applications Solid Explorer, CX File Explorer and FX File Explorer. They provide a convenient interface for managing hidden objects and often have built-in tools for working with archives and network storage.
When launched for the first time, such managers may request permission to access all files on the device. This is a required procedure for Android 11 and higher, which allows the application to see not only media files, but also data from other applications in the folder Android/data. Without this permission, you will not be able to find game logs or social network caches, which often take up gigabytes of space.
In the settings of most advanced file managers there is a separate privacy section where you can enable the display of files with a period at the beginning of the name. Some applications, such as Root Explorerrequire superuser rights to access the system partition /systembut to work with user memory /sdcard they work fine without rooting.
| Application | Required Root | Show hidden files | Additional. functions |
|---|---|---|---|
| My Files (Stock) | No | Yes (in settings) | Integration with Samsung cloud |
| Solid Explorer | No (optional) | Yes | Encryption, FTP/SFTP |
| CX File Explorer | No | Yes | Site analysis, garbage cleaning |
| Root Explorer | Yes | Yes | Full access to the system, editing |
⚠️ Attention: Download file managers only from official sources, such as Google Play Store or Galaxy Store. Third-party APK files may contain malicious code that will gain access to all your data immediately after granting permissions.
☑️ Selecting a file manager
Access to system folders via a computer and ADB
If built-in Smartphone tools do not allow you to find the desired file or access it; the most reliable method is to connect the device to a personal computer. Using software debugging USB and utility Android Debug Bridge (ADB) makes it possible to view the file system with rights that are not available for regular applications on the phone itself.
First, you need to activate developer mode on your Samsung Galaxy. Go to Settings → Phone information → Software information and quickly click 7 times on the item Build number. After the message about activating developer mode appears, return to the main settings menu, where a new section "Developer Options" will appear. Inside, find and enable the option USB debugging.
Connect your smartphone to the PC with a cable and confirm permission to debug on phone screen. On the computer where the package is installed Platform Toolsopen the command line and enter the command to enter the device shell:
adb shellAfter successful connection, you will be able to use Linux commands for navigation. For example, command ls -a will show all files in the current directory, including hidden ones. To search for a specific file throughout the system, you can use the command find. This method is especially effective for finding files that are hidden not only by the name attribute, but also by access rights.
What to do if the computer does not see the phone?
Make sure that the cable is working and supports data transfer, not just charging. Try a different USB port, preferably USB 3.0 (blue). On the phone screen in the connection notification, select the “File transfer” or “MTP” mode, and not “Charging only”.
Analysis of the Android/data folder and clearing the cache
Starting with version Android 11, the company Google has significantly tightened security policy, blocking access to the folder Android/data for most third-party applications. This is where cached game data, offline maps of navigators and temporary files of streaming services are stored. Finding and cleaning these files with a standard explorer on new versions One UI becomes difficult.
To bypass this limitation without root access, you can use a loophole through the "Device Manager" system application or use a file manager that requests special access through the system dialog. When you navigate to this folder, the system may warn you that changing files may cause applications to crash. Confirm the action to gain temporary access to the content.
Inside the folder Android/data you will find a directory com.android... with the names of installed app packages. Deleting the contents of these folders will safely free up space, but will reset settings within applications (for example, you will have to log in again or download levels in the game). This is a powerful tool to combat memory bloat.
- 📂 The folder
obbcontains heavy game files, clearing it will make the games inoperable. - 🗑️ Delete only the contents of folders corresponding to already deleted applications to avoid errors.
- ⚙️ To access
Android/dataon Android 13+, you may need to use utilities like X-plore or connect to a PC.
⚠️ Attention: Interfaces and access levels to system folders may change with security updates. Android. If the described method stops working, check the latest instructions for your specific firmware version on the official support portal or in the developer community.
The Android/data folder is the main place where “garbage” from applications accumulates, but cleaning it requires care so as not to lose progress in games and app settings.
Recovery of deleted hidden files and security
Sometimes searching for hidden files is due to the need to recover data that was deleted by the user or by malware. Smartphone file systems do not erase information instantly; instead, they mark the space as free for recording. As long as new data has not overwritten this sector, the chances of recovery remain high.
To search for traces of deleted files, you can use specialized software for a PC, such as Dr.Fone, DiskDigger or Recuva (if you have root access or are connected in debug mode). These apps scan the physical memory of the device, ignoring the logical structure of the file system, and allow you to find fragments of photos, documents or instant messenger databases.
However, it is worth remembering security: some hidden files can be created by ransomware viruses or Trojans. If you find a file with an extension .exe, .apk or a strange set of characters in the root directory, do not try to open it. It is best to scan the device with an antivirus built into the shell Samsung Knox or a third-party solution.
Is it possible to find hidden files without installing additional applications?
Yes, this is possible through the built-in My Files application if you activate the option to show hidden system files in the settings. You can also use a PC connection in MTP mode to view the folder structure through Windows Explorer.
Why can't I see the Android/data folder on the new Samsung?
This is a security limitation introduced in Android 11 and above. The system blocks direct access to this directory to protect application data. You can get around this through special file managers that require special access, or by connecting to a computer.
Is it dangerous to delete files starting with a dot?
Most of these files are service files (configurations, caches, markers). Deleting a file .nomedia is safe and even useful for photo recovery. Deleting other hidden files may cause applications to be reset or not work correctly.
How to find a hidden folder from other users on your phone?
If the phone was in the wrong hands, check the folder Secure Folder (Secure Folder), which is Samsung's standard data isolation feature. It's also worth checking hidden albums in the Gallery and archived files in Explorer.
Do you need root access to view all hidden files?
To view custom hidden files (starting with a dot), root access is not needed. They are required only to access protected system partitions, such as /system, /data (full access) and /vendor.
