The WinUAE trick sounds interesting. However, another option would be to remove your CD burner and install it temporarily into the Amiga (or perhaps even buy a new one, burners are dirst cheap these days anyway). That way you can use ABackup to write directly to the CD (if it supports that feature). Alternatively, all you'd need is a NULL modem cable, and transfer the file(s) over using ZModem (Hmmmm... haven't used that protocol in years...). Anyway, that should do the trick. Good luck!
