Fast File Encryption for Windows?

cryptoz wonders: "I've used numerous encryption applications for both Windows and Linux over the past few years and have always been satisfied. Until I realized I needed to start encrypting large files (say 10 to 30 GiB), or at least a large number of small(er) files. I found that everything I use seems to take hours and hours to compress, encrypt and shred. Not to mention decompressing, decrypting and deleting on the other end. Every web search I do on the topic seems to turn up mostly closed-source applications or snake oil, neither of which is acceptable. Does Slashdot have any suggestions for fast file encryption? I should make it clear that in my particular case, I do not need to have a perfect key or incredibly secure encryption, since it is not the weakest link (as I am susceptible to hardware key-loggers, CRT eavesdropping and the like). The encryption needs to be just strong enough, but most importantly, *fast*." This is a worthwhile question, but when dealing with files in the 10s of GB, can anything really be considered to be "fast"?

Dunno why noone mentioned it...

But you should look at TrueCrypt

Yes, a station wagon filled with tapes of 10GB+ files doing 80mph on a highway is going at a pretty fast clip in my opinion. YMMW.
