I'd like to be able to copy unencrypted files from a disk to an external storage (whatever kind), and then back. I would like that when copying to external storage, the files transparently get encrypted, and when copying from external storage, they get decrypted. This way, I'll see no change on my machine, but the archived files will remain safe.
I am using Windows 7 and would like a procedure integrated as a special Copy/Paste in the Explorer. No more clicks.
Is there a way to achieve that only using the built-in Windows resources ? Is there a simple utility that enables that ?
