Windows 7 sharing with Vista 64.
Some reason I can see all the other files just not Diablo-III-8370-enUS-Installer folder
Edit, I was reading on what could cause it and the folder was not shared in its parent directory and I did a copy with out the parent to the shared folder and I was unable to see the files until I changed the sharing options for the folder.
Works great! Copying 5 minutes remain at 10.9mb a sec.
One thing that I hate is the fact that my gig network on all computers seams to only copy at 10 mb even if I disabled my anti virus network shield.
