In view of the above principles , Enlarged .vmdk File is not weight loss , Even if you delete all the data , This file depends on the occupancy windows Your hard disk space will not change .

Post the link I read , There are many other ways , Not used for reference
Perfectly solve the problem that virtual machines occupy more and more hard disks 、 Out of memory error occurred while deleting snapshot
