A common issue with virtual environments (rdesktop, virtualbox, &co) is to have a common storage between real and virtual systems.

With vbox you can easily share a folder between guest and real host once you have installed Guest Additions. So

1. install guest additions
2. create a shared folder
3. # mount -t vboxsf mySharedFolder /mnt/

With rdesktop simply add the following parameter to

share a local directory with your remote host

# rdesktop winhost -r disk:Home=/home/rpolli
