EXAMPLE: I would use a command like:

"PKZIP -sMyPassWD U62011.zip player6.trn"

to encrypt a file before uploading it. The name of the file must be of the right form, but does not have to end in ZIP... the first word must be YOUR Robo user number. If you don't know your user number send Robo an email requesting "REPORT USER". If you suspect email failure, you can visit the web page for your game and there might be an email link (the reason for my high spam volume). If the game is a blind game, or you are a FREE player who has denied email. You can try making a change toyour player config to permit an email link. FREE players in blind games have no other way than the email command to get their user number. The password is the first 8 non-blank characters of your codephrase.
