And, as someone else already pointed out, another AES utility may not
be able to decrypt Winzip's AES encryption.

Then using your files is also, unless you write or download an
encrypter you feel secure with and can convince them that they have no
choice but to download it and use it to decrypt.

Yes, I was. I understand the situation now. As I said, if you want
to encrypt the file, either before or after zipping, you'll need the
same program at both ends for most good encryption methods. And, as
someone else said, Blowfish is pretty good and available free.
