compacting a VirtualBox Windows storage container

Posted 10-19-2011 at 10:47 PM by neonsignal

After a Windows client has been used inside VirtualBox for some time (particularly if large files have been removed), it can be useful to compact the storage container image (VDI) by removing unused space.

However, in running the tests during the past week, I discovered something unexpected.

Windows XP and Linux have very different methods of assigning weight to particular tasks.
