I'd recommend Safehouse Explorer, free and versatile. From http://www.safehouse...feHouseExplorer.aspx
TSA reviewer said this abot SE:
"SafeHouse Explorer is easy to use, but it has a flaw that could leave your data exposed. The SafeHouse Explore interface is a pseudo Windows Explorer window, with a few encryption functions included.
The problem is, you cannot create files directly in the interface. That forces you to create unencrypted files outside the volume, and then copy them to the volume. Of course those unencrypted files still reside on your hard drive. There is a "Secure Delete" function to securely delete external files, but you need to remember to always do that.
Fortunately, there's a way around that security hole. If you open a real Windows Explorer window after opening a volume in SafeHouse Explore, you'll find a SAFEHOUSE drive listed there. You can work within that encrypted window -- create files, delete files, edit files, etc. -- just like you would in any other drive. There will be only one copy of your files, and they will never be stored in unencrypted form. If you're careful how you use SafeHouse Explorer, it's a safe, simple program."
