I have virtualbox installed on my mac.  I have several virtual
machines, the one that's causing problems is my windows xp machine.  I
want to transfer files from my mac to my windows machine.  I tried
sharing a folder but can't find it in windows - I tried putting a CD
in but windows can't read it - I installed Filezilla FTP Server - but
now I'm suck with how to set that up so that I can FTP from my Mac to
the Windows Virtual Machine.

Any tips from the experts?

Thanks in advance,
Nicole
