How To Password Protect Files In Android For Privacy?
- Install ES File Explorer if you have not already done so.
- Open ES File Explorer
- Browse to the file or folder that you want to password protect.
- Select a file or folder by long pressing.
- Open the 'More' menu and tap Encrypt.
- Input the password and tap OK.
Note: When you encrypt a folder, all files in it are encrypted. You can still open the folder without a password, but files will open with password only.
- Install File Commander
- Tap the hamburger icon to open the sliding menu
- Toggle ON 'Secure'
- Enter a new password. Important note (Read carefully): This password cannot be recovered if you forget it. You can create a new password but files encrypted with the old password will not open with the new password.
The next step after creating the password is to select the files that are to be secured.
