ENCRYPT EVERYTHING!ZP Crypt File Browser encrypts and decrypts all kind of files. If you have any file you want to encrypt, just choose this and encrypt giving it a password. But please remember your password. Once forgotten, the passwort can't be recovered because it is NOT saved anywhere.
Once a file is encrypted, it is still there, at the same place where it has been before encryption, but you won't be able to open or execute it. For decryption choose your file again and after you've entered your password it's ready to use again.
If a file is not encrypted, you can open it out of ZP Crypt File Browser. After decryption the decrypted file will be opened out of ZP Crypt File Browser.
