Im on a hunt for some sort of USB drive security software. What I'm looking for is something that I can load onto the thumb drive and would allow me to secure or encrypt my files. I carry work files to and from work and would prefer it if the files were somewhat secure. I know their is mac specific software out there and also windows specific software out there but I'd like to find something that would work on both platforms. Even something that would just password protect a folder would be fine.... any ideas?
