If you just deleted the Fusion program, the Windows VM is still intact and taking up space. I haven't used Fusion is quite some time and have forgotten where it stores the VM and other VM related files.
Try doing a SpotLight search to see if you can find where they are stored and then manually delete them. The Windows VM file will be large - the same size you originally assigned to it.
Sorry I can't be of more help. Perhaps someone else will reply with the exact location of the VM files.
Regards.
How do i do a Spotlight search? I am new to MAC and am having problems finding things. I know Windows is still on there. Just don't know how to take it off......
1 Power off all running virtual machines, and quit VMware Fusion.
2 Browse to the Virtual Machines folder (usually in your <user>/Documents folder) and select the machine you want to delete.
3 Move the virtual machine file to the trash.
