Am I going to lose any data?

You could run TreeSize on the host server to see where space is being consumed and then delete unnecessary files:

You could also run CCleaner if you still trust it

Go to the Settings of the VM in HyperV Manager, go to the VHD(x) in question (state MUST be off, not saved!) Click on Edit and then follow the wizard to Compact (this will take some time, but if memory serves USUALLY not more and 15-30 minutes, though clearly it depends on the size and type of the disk).

The vmachine is the only thing on that drive. Funny thing is that when I look at the properties it shows the flies are 420gb but the drive itself shows 446GB used.

You shouldn't, but that's why you have backups, RIGHT?

The process doesn't normally lose data, but you're mucking around with disks (virtual or otherwise) - it's unwise not to be prepared for the POSSIBILITY that something goes wrong.

ASKER

It says edit is not available because checkpoints exist for this virtual machine. Can I just delete the checkpoint?

I deleted the checkpoint and it started normally. So I just need to compact that disk right?

I'm not sure about a saved/paused-Critical situation, HOWEVER, in 2012 R2 and later you can delete checkpoints while the VM is running (merger takes longer).
