Android-SecuredFiles

Android application copies files from Downloads into internal app directory and protects access with password.

Screens

         

How it works

1. Set password on first launch.
2. Click floating button add.
3. Select files from Downloads dir and click done.
4. Use Navigation Panel to filter files by types.
5. Use Operation menu to change password.

Security notes

• Application encrypts only user password and does not encrypt file's content, so root user can access files.
• There is no way to restore password because application does not store plain password text.
