Android smartphones over time turn into huge repositories of media files, where images from instant messengers, cached pictures from browsers and advertising banners of applications are mixed with your personal photos. This creates chaos in the standard gallery, forcing you to scroll through hundreds of unnecessary photos in search of the desired frame. Regular deletion of files is often impossible, since they are needed for apps to work, but displaying them in the general feed is completely unnecessary. This is where a special system file comes to the rescue. .nomedia.
This hidden marker tells the operating system and media scanner that this particular folder and all its subdirectories should not be searched for media files for indexing. Creating such a file is the most effective way to clean up your gallery without deleting data. You can hide entire albums with memes, screenshots or service images, leaving them accessible through the file manager, but invisible to the eye in the Gallery application.
In this article we will examine in detail the creation process .nomedia in various ways: from using built-in tools to connecting to a computer. We'll also look at common errors that users encounter when trying to hide folders and how to resolve them. Understanding how the Android media scanner works will allow you to flexibly manage the visibility of content on your device.
The principle of operation of the .nomedia file in the Android system
The Android operating system uses a special service called Media Scanner, which constantly scans the internal memory and SD card for new media files. As soon as the scanner detects an image, video or audio, it adds a record of it to a special database. It is from this database that gallery applications, music players and desktop widgets draw data.
File .nomedia acts as a stop signal for this process. When the scanner encounters a file with this name (regardless of its extension or content, it is the name that matters), it skips the current directory and does not scan its subfolders recursively. This means that if you place this file in the root of the folder WhatsApp/Media, then all subfolders with images will no longer appear in the gallery.
It is worth noting that the file does not physically delete media. It only changes the visibility flag for applications using the system's default media provider. Some third-party galleries may ignore this marker and show all files in a row, but Google's standard Photos app or Samsung's Gallery strictly adheres to this rule.
⚠️ Note: Once a file is created, changes to the gallery are not always immediate. The system may need time to restart the scanning process or manually clear the media storage cache to apply the new rules.
Preparation: choosing a tool to create the file
Before you start creating a token, you need to decide on the tools. On modern versions of Android (starting from 11 and higher), access to the root file system is limited by security policies Scoped Storage. This means that the standard file manager may not allow you to create files with a dot at the beginning of the name in certain system folders.
To bypass these restrictions, it is recommended to use advanced file managers such as Files by Google, Solid Explorer or FX File Explorer. These applications have the necessary permissions to work with hidden files and allow you to create objects with non-standard names. You can also use a connection to a PC, where Android restrictions do not affect the file system of the drive.
- 📱 Built-in file manager: Suitable for basic operations, but may block the creation of files starting with a dot in system partitions.
- 💻 Connecting to a computer: The most reliable way to create a file in any folder without access restrictions Android.
- 🛠️ Third-party utilities: Specialized applications like "Nomedia Generator" that automate the process with one click of a button.
The choice of method depends on your skills and the availability of additional equipment. If you have access to a computer, the USB cable method will be the fastest and most secure against permissions errors. Otherwise, installing a quality file manager from Google Play will be the best long-term solution for managing your file system.
Method 1: Create through a file manager on your smartphone
This is the most common method and does not require connecting to external devices. First, open your file manager and go to the directory that you want to hide from the gallery. For example, this could be a folder Download/Telegram Images or any other user directory.
In the action menu (usually three dots or the "More" button), find the option to create a new file. In some managers it is called “Create file”, in others it is called “New document”. You will need to enter the file name manually. It is critically important to start the name with a period: .nomedia. The file extension (after the second dot) can be omitted at all or written in any way, for example .nomedia.txt, but the system recognizes it by the first word.
☑️ File creation algorithm
After saving, the file may not appear in the list immediately, since by default file managers hide system objects. You need to go to the settings of the explorer itself and enable the option "Show hidden files". Only after this you will see the created object, making sure that the operation was successful.
⚠️ Attention: On some shells (for example, MIUI or ColorOS), the creation of files with a dot at the beginning may be blocked in folders
Android/dataorAndroid/obbwithout providing special permissions through the system settings.
Method 2: Using a computer and USB cable
If the mobile file manager causes difficulties, connecting to a PC is a universal solution. Connect your smartphone to your computer via a USB cable and select the file transfer mode MTP in the notifications on the phone screen. On your computer, open the removable device that appears.
Find the desired folder in the directories structure of your smartphone. Right-click on the free space, select "New" -> "Text Document". Name the file .nomedia. Windows may warn you that changing the extension may make the file inaccessible - confirm the action. Make sure that the file name is exactly .nomediaand not .nomedia.txt.
File name: .nomedia
Extension: (missing)
Once created, safely remove the device or simply unplug the cable. The file will immediately appear in the phone's memory. This method is especially useful if you need to create such markers in a dozen different folders at once, using the power of the desktop file system to copy in bulk.
If Windows does not allow you to rename the file to .nomedia, create a file called "nomedia.", and then rename it by removing the dot at the end via the Command Line or Total Commander.
Method 3: Using specialized applications
For users who do not want to deal with the file system manually, there are ready-made solutions in the application store. apps like Nomedia Scanner or functions in advanced launchers allow you to add markers to one folder or scan the device for folders without such files.
The interface of such utilities is usually extremely simple: you see a list of directories, and opposite each there is a switch or a “Hide” button. When clicked, the application automatically generates and places the file .nomedia in the selected location. This saves time and reduces the risk of typos when entering a file name.
However, it is worth remembering that installing additional software increases the load on the system. If you need to hide just one or two folders, using the built-in Explorer or PC will be a more rational solution than installing a separate application that may request unnecessary permissions.

|---|---|---|---|
| File manager | Medium | High | Depends on access rights |
| Computer (USB) | Low | Average | Maximum |
| Special. applications | Low | High | High |
Problem solving: the file has been created, but the pictures are visible
A common situation: you created a file, rebooted the phone, but the images are still displayed in the gallery. This happens because the media provider's database already contains indexes of these files, and the mere appearance of a new file does not always trigger a full rescan.
To force a database update, you need to clear the system application data Media service (Media Storage). Go to Settings → Applications → Show system processes. Find "Media Service" or "Media Storage" in the list. Click "Memory" and select Clear data.
After this operation, the gallery may temporarily become empty. Don't panic. Reboot your device and give it 10-15 minutes of rest. At this time, the system will scan the memory again in the background, take into account new files .nomedia and correctly create an image library without hidden folders.
Why is data clearing safe?
Cleaning data from the "Media Service" application does not delete your photos, music or videos. It only deletes the index database, which will be recreated automatically on the next scan. Your files remain in place, completely safe.
⚠️ Warning: The rescanning process can significantly drain the battery and load the processor. It is better to perform this procedure when the phone is connected to charging and not actively used.
The subtleties of working with Android 11, 12, 13 and later
Starting with Android 11, Google has implemented strict restrictions on access to folders Android/data and Android/obb. Even with superuser rights or through some file managers, the creation of files in these directories may be blocked. This is done to protect application data from unauthorized modification.
In such cases, the standard creation method .nomedia may not work inside these protected directories. An alternative is to use the function .noindex (although it is less common for media) or adjust the visibility within the source application itself, if such an option is provided by the developer.
Also, the behavior of the scanner has changed in new versions of the OS. It can now ignore .nomedia some system paths intended for mandatory indexing (for example, default camera folders). In such situations, you can hide photos only by moving them to another, custom folder, where you control the presence of the marker.
On modern versions of Android, the creation of .nomedia in system folders is limited by the Scoped Storage security policy, so it is better to use custom directories to hide files.
Is it possible to create a .nomedia file without an extension?
Yes, the file should be named simply .nomedia without any extension after this word. If you create a file .nomedia.txt, the system may not recognize it as a marker, although in some cases this option will work. The safest way is to create a file without an extension.
Will .nomedia delete my photos?
No, the file .nomedia does not affect the physical presence of files on the disk. It only hides them from gallery apps and music players. You will still be able to find and open these files through any file manager.
Why did the gallery become empty after creating the file?
Most likely, you placed the file .nomedia in the root directory of the internal memory or in the DCIM folder. In this case, the scanner ignores all media files on the device. Delete the file from the root and leave it only in those folders that you want to hide.
How to delete a .nomedia file?
To restore visibility to folders, you just need to delete the file .nomedia from the corresponding directory. After this, it is recommended to clear the media service cache or restart the phone for the changes to take effect.
Does this method work for video and music?
Yes, the principle of operation is universal. The file .nomedia hides all types of media files (images, videos, audio) from standard players and galleries, preventing their indexing in the corresponding databases.
