Compact a virtual hard disk

You can compact a virtual hard disk in order to reclaim unused space. If a disk has empty space, this process reduces the amount of space the virtual hard disk occupies on the host system drive.


  • the virtual disk should not be mapped or mounted.
  • disk space must not be preallocated for the virtual hard disk.
  • if the virtual hard disk is an independent disk, it has to be in persistent mode.

Here is how you can compact a virtual hard disk:

1. Power off the virtual machine.

2. Select the virtual machine from the library and go to Player > Manage > Virtual Machine Settings:
