A few months (ok, longer) I tried to get my Win 7 pc to communicate with my Amiga and it flat out refused. I researched the web and found Win 7 hates connecting to other computer OS's -- and Samba running on the Amiga didn't work either. Either you can drop back to XP or earlier, wish for devine inspiration, or set up an inexpensive server (which is what I did) and FTP files back and forth.
If anyone has an Amiga Forever solution running on Win 7, please say how!
P.S., I keep all my Amiga downloads on the server so I can get access from any rebuilds I am working on; it also has my movie and music collection for my Roku devices.
