Using Free Disk Space Wizard, you can compress the virtual machine's hard drive(s) and remove various unnecessary files to free up disk space.
To quickly compress the disk(s), remove unnecessary files, and free up disk space:
Shut down the virtual machine.
Choose File > Free Up Disk Space.
The Free Disk Space Wizard shows whether you can reclaim any disk space by removing virtual machine snapshots, cache files, and various unnecessary files such as statistics, memory dumps, and crash dump files generated during the virtual machine life cycle.
You can also conserve disk space by compressing virtual disks manually or clicking Reclaim on the General tab of virtual machine configuration.
