About this app

File Locker allows you to manage files and prevent unwanted access to your private files with PIN, pattern or password lock.

★ How it works?
This app locks file by encrypting the file content with the password and then hiding the encrypted file. It does not move the file to another folder. So if you delete the folder, the locked file will be deleted as well.

★ Please note:
The out of memory error may occur when the free storage of device is not enough to lock/unlock file. For example, please note that to unlock a 100 MB file, your device must have at least 100 MB of free storage.
So, in this case you may need to free up your device storage to be able to unlock the file.

Features:
★ Simple File Manager
★ Safe and easy to use
★ No unnecessary permissions
★ Use Advanced Encryption Standard to lock files with password
★ Advanced security settings:
- Prevent uninstalling File Locker by activating its device admin

FAQ:
• How if I forget the lock screen?
Because this app doesn't want to use Internet access (for your privacy), so it doesn't support password recovery via internet such as email.
If you forget password, you can clear app data or re-install app to reset password.
But if you cannot recover the old password, you will not be able to unlock the files locked before.
So please try to not forget the password!

IT WORKS WONDERFUL . THE FILES ARE LOCKED IN IT'S OWN DIRECTORY/FOLDER AND CAN BE EDITED AFTER UNLOCKING THEM . IT SHOULD HAVE GATHERED MUCH BETTER RATING. HAVE TRIED SEVERAL OTHER APPLICATION BEFORE THIS BUT DIDN’T FULFIL MY NEED.

Avoid this "File Locker"app (with icon of a padlock). I paid to eliminate the ads, and the ads became worse and repeatedly interrupted operations and repeatedly forced re-login with password and restart of operations.

I think this app works decent. I am wondering if it's possible to delete all the encrypted files if app were to be uninstalled? And if the app were uninstalled and say the files remained then if the app were red downloaded would you be able to access them and would you ever be able to delete them from your phone?

Hello, Thank you for using my app! Please share it with your friends if possible. Thanks! About your questions, if you uninstalled app, the encrypted files are still in the device storage, and if you reinstall app and setup the same password then you can read file again
