Thanks for the tips. After I sent this, I realized something...it doesn't really matter how much I encrypt it. The decrypted zip file needs to reside either on the computer's local drive or the flash drive at some point, and deleted files can be recovered. That's ok though...my intention is to keep anyone who happens to find the thing from browsing every file on the flash disk easily. I've already accepted that if they really really really want to view the data, there are mutiple ways to do so. As long as it's supporated on mutiple platforms and isn't as easy as plug in USB key, browse drive, open files. -- Andrew S.
