Shrink a vdi VirtualBox disk image
- Run defrag in the guest (Windows only)
- Nullify free space:
With a Linux Guest run this:
cat /dev/zero > zero.fill;sync;sleep 1;sync;rm -f zero.fill
With a Windows Guest, download SDelete from Sysinternals and run this:
sdelete.exe c: -z
- Shutdown the guest VM
- Now run VBoxManage's modifymedium command:
On Linux:
vboxmanage modifymedium disk /path/to/thedisk.vdi --compact
