Thanks a lot everyone, I'll give them a try! Edit: I tried TrueCrypt but it seems only to create encrypted volumes (drives). What I'm looking for is an application with a particular function where I choose what files to encrypt with a password and what not, just like when you right-click on a file(s) to archieve them using winrar or winzip. ->I suppose GnuPG is for linux boxes, I need smth that works on winxp.
