BACKUP FIRST, OKAY?
To clean up the mess, I had to remove the following files:
.VMEM (VMWare Server paging memory file)
It will only appear if the virtual machine is running and will be left it if it has crashed.
.LOG
Log files that keep a record of VMWare Server activity
.NVRAM file
.VMSD
This is a centralized file for storing information and metadata about snapshots
Also, I found a couple of snapshot files are no longer used. The following files can be removed:
.VMSN
This is the snapshot state file, which stores the running state of a virtual machine at the time you take that snapshot
.LCK
indicating that certain files are locked
Once I removed these files disk had nearly 50GB of free disk space.
Don’t Remove:
.VMX
This is the primary configuration file, which stores settings chosen in the New Virtual Machine Wizard or virtual machine settings editor.
.VMDK or .#.VMDK – this is a virtual disk file, which stores the contents of the virtual machine's hard disk drive.
