Locate the disk image: On Ubuntu, VirtualBox stores your machine data in " $HOME/VirtualBox VMs " by default.Virtual operating system: Windows XP SP3.Aim: Grow my disk image storage from 10GB to 80GB.Fortunately, VDI disk images can be increased in size, but my Googling resulted in a variety of methods which were all a bit confusing, so this post summarises what I had to do for my exact situation, which I didn't come across anywhere else.

I originally created a 10GB virtual disk image, but soon realised that wasn't enough space if I wanted to also backup the 64GB iPad completely. To do this I use the excellent VirtualBox software to run an Windows XP virtual machine within Ubuntu. My desktop computer runs Ubuntu Linux (on a Mac Mini!), but sometimes I am forced to use Microsoft Word to edit a document that LibreOffice/OpenOffice Writer can't handle, or use iTunes ( ech.) to fix the kids' iPad.
