I have removed the Checkpoint for the VM on a Hyper-V 2012 R2 Host machine.  However, when checking the folder, Virtual Hard Disks, the *.avhdx file is still there.  It is huge, 182 gb.  The VM's *.vhdx file is 214 gb.  How can I remove the *.avhdx file to make more room?   Do I need to run a PowerShell Command to remove it?

Have you removed *all* the checkpoints? You can chain them or have multiples after all. And have you verified the status isn't still "merging?" Or is the VM itself set up yo use a differencing disk? Those are also avhd. Hyper-v is very good at cleaning up after itself. If the file is still there, I'd strongly suspect it is still in use.

They Hyper-V Manager shows all the Checkpoints are removed.  It has finished merging since I removed them on Saturday.  The VM is not setup to use a differencing disk.

Well, if it were me, I'd shut down the VM. Rename the avhd, and restart the VM. Look for missing/lost data or errors, and if all is well, move the avhd off the system to cold storage and eventually delete it.

The suggestion Cliff Galiher had given worked for me.  Before I did it, I opened the Hyper-V Manager and under Actions, I inspected the disk, or ahvdx file.  I have not seen errors or missing data.  However, these two articles did help me with my decision and provided ma a backup plan.
