        You are - trust me.

        That is a completely accurate description of the process!

        Sorry, you're wrong. Read the above paragraph again and then
read this:

        What you'll see if that Base64 encoding is applied to BOTH
forks and that when received on a Mac, those forks are properly
reassembled. On a Windows box, because it doesn't know from multiple
forks, the resource fork is simply ignored. The fact that the
AppleDouble file has been Base64 encoded is irrelevant - it's the
fact that Windows doesn't know from multiple forks.
