virtualbox.org

I'm trying to share files between host and guest.
Host = Mac OS X 10.6.7
Guest = Windows XP Pro SP3

I tried making a shared folder. I specified the folder on the Host but where can I find it on the Guest?
I also tried sharing a USB flash drive but it never appeared on the Host.

I'd like to take whichever corse of action is easiest. Thanks in advance.

Use the shared folder of VBox and install the guest additions in the guest.
See Chapter 4.3 Shared folders in your VirtualBox users guide.
