I needed to move one of my VirtualBox setups to another computer but the disk image was huge and wouldn’t fit on my thumbdrive. Digging around in the VirtualBox settings I noticed an import/export function.

VirtualBox Export/Import

The original disk image was 4.13GB. Exporting it resulted in two files that totalled 1.75GB! That will easily fit on my 2GB thumbdrive (or Dropbox).

Exporting (and importing) is a straighforward process. Select export – you will be given the opportunity to define some configuration values for your machine, then simply define the export filename. Import is the reverse – select import – location you exported file and proceed. Exporting my 4GB disk took about 25-30 minutes.
