I have migrated a Virtual Machine from version 10 to 11, in the process I remember been asked to 'Clone' or to 'Alter'... I clicked 'Clone' but now I have huge ammount of extra space in that virtual machine, I think I had to select 'Alter' :(
Is there some way I can clean that Virtual Machine? delete the extra space made by the original files? or maybe revert, or anything helpful?
