If someone says you want to use this kind of tool to verify the security of passwords or recover them, that would be a joke, I think. After all, a rule for secure enough password is very simple - Uppercase + Lowercase + Number+ Symbol (and > 8 characters), there is no need of any tool to validate it at all. The same for wireless network password, restoring it is meaningless - just reset the router to default, which is the most efficient way. So, obviously they are designed for passwords cracking only.

As we all know, the common way of deleting a file/folder is just to mark its directory entry or occupied cluster area. So the fact is all these so-called "deleted" files/folders are still lying there. And using the ancient DOS command 'Undelete' or Norton's Unerase command can be restored with ease.

Any deleted files, as long as they have not been overwritten, in theory that is completely can be recovered, of course, that needs to pay the corresponding cost. Therefore, for very privacy data, such as photo, video, office file... you'd better use special software to shred them rather than just right click to delete.

For archived files (mainly RAR or ZIP format), that is very embarrassed and depressed in two cases. First, the archive file downloaded from the Internet prompts you need password to extract it out; Second, some important archive was protected using your own password, but you just forgot it. If so, turn to the Advanced Archive Password Recovery for help.

Kakasoft Folder Protector (KFP for short, now called LockDir) is a very powerful, user-friendly and practical security utility, which is designed to encrypt and password protect folders & files on any types of storage devices, in order to protect your personal valuable or privacy data with ease.
