What does the last line mean?
I thought this is a drag-drop file copy feature like VMWare.
I tried that. But I couldn't copy by drag-drop, ctrl-c ctrl-v either.
Edit:
I mean VBox 4.0 beta, not 3.x

No, the current versions of VirtualBox (3.x) do not support file drag'n'drop between the host and the guest.
There is no additional information in the 4.0 release notes but it seems that they finally are implementing this feature.
