Just thought I'd share this as it's caused me a headache on my new Win 7 x64 PC.
I use virtualisation and have an XP Guest - the file transfer between the Host and Guest was totally abysmal - unusable in many cases.
After sniffing around online I found out the following:
If you disable 'Large Send Offload v2' for both IPv4 and IPv6 on your network adapter (under properties -> advanced) it should speed up the access between Windows 7 Host and XP Guest.
This worked for me wonderfully - it may also need it on other virtualisation platforms or to other OS guests. It seems if your host is XP it's not an issue.
Hope this helps someone,
Is this under all virtualisation packages? Haven't actually noticed a problem with either VMWare Workstation or Virtual XP Mode packaged with Win7 itself. I do use, however haven't yet on 7 Virtual Box and full blown Virtual PC so wondered if it was specific to those.
This may well not be with JUST virtualisation - I've got a new Win 7 laptop - transfer times between it and my XP PC were absolutely awful.
Turn off the 'offload' bits on 7, reboot and all was well...
I'd make the assumption it's for all virtualisation platforms - but give it a go, you may find one that it doesn't need it.

Very useful to know. Thanks for sharing
Been playing a bit recently and yeah, have noticed this on XP transfers. Not a huge issue, as the sooner XP is gone the better as far as I'm concerned Obviously that sentiment won't apply in many educational establishments so it's worth noting.
