FlashLock

FlashLock is a folder locking utility. Entire folders can be encrypted into one file. With the appropriate password the file will open into a standard Windows folder and can be manipulated like any other folder and when it is closed the folder will be re-encrypted. Unlike other utilities which only encrypt each individual file and leave them in place, FlashLock encrypts all the contents of the folder and its subfolders into one single file and the individual files in the folder can neither be listed nor viewed without decryption. Uses the conventional encryption features of PGP.
