Today I was testing some OS image within various Virtual Machines and at some stage noticed my available space on the disk became lower and lower. Although after each test i had deleted the VM entirely somehow i must have overlooked one or the other. So where are those BIG files on your local disk that are eating your disk size ?
Well I launched WinDirStat that one had recommended me once, and is really a great tool. WinDirStat provides a graphical overview of your disk, allowing you to quickly identify where the BIG files are that can be deleted to gain space again.
More information and download on the WinDirStat site.
