Hello,

Compacting a virtual hard disk reclaims unused space in the disk. If a disk has empty space, this process reduces the amount of space the virtual hard disk occupies on the host drive. You must power off a virtual machine before you compact its virtual hard disk.

You cannot compact a virtual hard disk if disk space is preallocated or if the virtual hard disk is mapped or mounted.

For similar tasks, it is highly recommended to take a valid backup before (for your VM and for your data), because in IT shit happens

compact reclaims unused space in the disk, so it is unaware from data.

But recommended to take a backup in case needed.
