## Description

File Locker lets you manage and protect private files (photos, videos, documents) with PIN, pattern, or password lock. It encrypts the file content and hides the encrypted file without moving it to another folder, so deleting the folder will delete the locked file.

Key features include a simple file manager, safe and easy to use, no unnecessary permissions, AES encryption, and options to prevent uninstalling via device admin. Note: low storage can cause out-of-memory errors when locking/unlocking. Password recovery is not available online to protect privacy—reset by clearing app data or reinstalling.
