How to make a secret folder on Samsung: all ways to hide files on Android

Do you want to hide personal photos, documents or correspondence from prying eyes right on your own Samsung Galaxy? Secret folders on Android are not a myth, but a real privacy tool that is available even without installing third-party applications. In this article we will look at all working methods creating hidden storage on smartphones Samsung with a shell One UI 5/6, including models Galaxy S23/S22, A54/A34, Z Fold/Flip and others.

Many users mistakenly believe that that hiding files requires root access or complex technical manipulations. In fact, Samsung offers built-in solutions, and third-party applications from Google Play extend capabilities to military-grade encryption. But how not to get confused in the settings and choose a reliable method? We tested each method on current firmware and collected step-by-step guide with nuancesthat cannot be found in standard manuals.

Important: some methods require preliminary configuration Secure Folder or activation Knox — these functions are not available on all models and may vary depending on the firmware region. If your smartphone does not support built-in tools, the article has alternative options using third-party applications and even hidden capabilities of the file manager.

1. Built-in Secure Folder function: the official method from Samsung

Secure Folder is a secure storage based on technology Samsung Knoxthat isolates your files from the rest of the system. The folder is encrypted by hardware, and access to it is protected by a password, fingerprint or face scan. This method Samsung is recommended as the most reliable, but has limitations: for example, some banking applications can block work inside Secure Folder.

To activate the function:

1. Open Settings → Security and privacy → Secure Folder.
2. Click Start and log in through your account Samsung (required!).
3. Select a blocking method (we recommend fingerprint + PIN code for double protection).
4. After creating a folder, it will appear on the main screen and in the application menu as a separate icon.

Now you can transfer files to Secure Folder via:

• 📁 File Manager: select files → Share → Secure Folder.
• 📷 Gallery: select photo → Menu → Move to Secure Folder.
• 🔗 Context menu: hold your finger on the file → Move to Secure Folder.

⚠️ Attention: If you delete your account Samsung or reset your phone to factory settings, access k Secure Folder will be lost. Restore data without a backup impossible —even in a service center.

2. Hiding folders through a file manager (without a password)

If you do not need military-grade encryption, but just want to hide the folder from casual glances, you can get by with standard means Android. This method does not protect data from targeted searchesbut makes them less noticeable in the interface.

Instructions for Samsung My Files:

1. Open the application My files (or any other file manager).
2. Go to section Internal storage or SD card.
3. Create a new folder: click ⋮ → Create a folder.
4. Add a dot at the beginning of the folder name, for example: .secret_photos.
5. Move the necessary files to it.

Now the folder will disappear from the standard view, but will remain accessible:

• 🔍 Through a search in the file manager (enter the name without a dot).
• 📂 Manually along the path /storage/emulated/0/.secret_photos.
• 💻 When connecting to a PC via MTP (displayed as hidden).

⚠️ Attention: This method does not work in Google Photos and some galleries - they scan all folders regardless of name. For reliability, combine it with ZIP archiving with password (see section 4).

3. Applications for hidden folders: top 5 solutions from Google Play

If built-in tools Samsung are not enough, third-party applications offer advanced features: AES-256 encryption, disguise as a calculator, remote data erasure and even protection against screenshots. We tested dozens of apps and selected those that actually work One UI without conflicts with Knox.

Comparative table of popular applications:

Recommendations for selection:

• 🔒 For maximum security: Hide Something or Private Zone (AES-256 + masking).
• 📸 For photo/video: GalleryVault (optimized for multimedia).
• 💰 Free solution with the cloud: KeepSafe (but there are advertisements).

⚠️ Attention: Some applications (for example, Vaulty) may conflict with Samsung Knox and cause errors when updating the system. Before installation, check the reviews for your smartphone model.

Step-by-step guide:

1. Open My files and select files/folders for archiving.
2. Click ⋮ → Compress.
3. Select format ZIP (not RAR —it does not support encryption in the standard manager).
4. Activate the option Encrypt ZIP and enter the password (recommended 12+ characters with numbers and special characters).
5. Save the archive in a safe place (for example, in Secure Folder).

To extract files:

• 🔑 Use My files → Extract and enter the password.
• 💻 On PC: any archiver (7-Zip, WinRAR) with support for ZIP encryption.

Important: standard ZIP encryption in Android is vulnerable to brute force attacks. For critical data, use AES-256 through applications like 7Zipper or RAR.
