first you have to share a folder with the VM: Virtualbox Mount shared folder

  1. reboot the VM

on the linux-guest open up a terminal:

2. check out what your user id is (uid)

cat /etc/passwd|grep YourUsername

3. become root & mount

mount -t vboxsf -o rw,uid=1000,gid=1000 SHARENAME /media/MOUNTPOINT

vboxsf not vboxfs!

or one will get error message: mount: unknown filesystem type ‘vboxfs’
