Ok, so what I want to do is lock a folder, and have some sort of a 'key' on perhaps an USB thumbdrive. I wanted to google it, but I just don't know what to search for. The software should be able to lock the a specific folder, even if that folder is inside another folder. But if there is some sort of software that can "lock" a specific file, that would do just as good. Should have a rather good encryption. EDIT: Found something called "Folder Lock". Anyone ever tried this one?
