Excellent program with a good interface. It's my new favorite. I would like to see a stealth mode where the locked file masquerades as a different file type, like .dat or .dll. This is similar to hiding cash in a fake 7up can in your fridge.
A serch mode in the program can identify stealth files on a computer so you can select the one you want to unlock. Handy if you forget the file name you used to hide the file.
