We carry more and more of our digital lives with us on our Android phones: intimate photos, work documents, copies of contracts, bank details… and, in short, a lot of information that We don't want just anyone who picks up the phone to see it.Locking the screen with a PIN or fingerprint is the first line of defense, but it often falls short, which is why many opt for create a secret folder.
For that second layer of security there is the Secure Folder, a feature found on Samsung mobiles (Secure Folder in One UI) as in the Google Files app and in layers like Moto Secure. Thanks to it we can save files in a space protected by PIN, pattern, password or fingerprintseparating them from the rest of the device's content and preventing them from appearing in galleries, searches, or third-party apps.
What is Secure Folder and why should you use it?
The Secure Folder is basically a private container within the phone where we can store files with encryption and restricted accessOnly someone who knows the configured locking method (PIN, pattern, password, or biometrics) will be able to enter and see what's inside.
On a technical level, this function takes advantage of the Android encrypted storage to protect dataThis means that even if someone physically removes the internal memory, they will not be able to read the files stored in the Secure Folder without the corresponding access key.
In addition to that encryption, Secure Folder adds very useful protection for everyday privacy: The files saved there don't appear in the usual apps.They are not shown in the photo gallery, the video player, or file search results, and cannot be opened from third-party applications.
This private folder concept is available in various forms depending on the phone: Samsung integrates its own Secure Folder into One UI, Google offers a Secure Folder within the Files app, and Motorola phones have... Secure folder within the Moto Secure app and security settingsThe philosophy is the same; only the menus and the names of some options have changed. If you need guidance on organizing folders, see [link to relevant documentation]. this step by step guide.

In recent versions of One UI (starting with Android 8.0), Samsung changed the name of the folder encryption feature. What was previously labeled “Encrypt” is now called “Hide Secure Folder”This option is especially useful if you want to ensure that no one even knows you're using this private space.
When you disable Secure Folder from the corresponding icon in the Quick Settings panel, the system plays a double game: It encrypts the content while simultaneously hiding the app icon.The result is that the Secure Folder stops appearing among your apps and its functionality is disabled.
While hidden, applications hosted within Secure Folder will not run, will not receive notifications, and You won't see them in the Settings menu or in the sharing panels.They will only become visible again when you reactivate the Secure Folder from the corresponding settings, entering your locking method.
It's worth bearing in mind that, while this option improves discretion, if You forget your PIN, pattern, or Secure Folder passwordYou will not be able to regain access to the interior. Security is designed precisely to prevent anyone from bypassing that barrier, including the brand itself.
