  • Hi,

    Thanks for your question.

    The VM’s checkpoints (or called snapshots preciously) are stored as .avhdx files in the same location as the .vhdx files for the virtual machine. When you delete a checkpoint, then the avhdx files will be merged to parent disks automatically. Once completed, the checkpoint's .avhdx file will be deleted from the file system.

    You should not delete the .avhdx files directly. To cleanly delete a checkpoint: In Hyper-V Manager, select the virtual machine. In the Checkpointssection, right-click the checkpoint that you want to delete, and click Delete Checkpoint.

    Please refer to the following article for the details,

    https://support.hostway.com/hc/en-us/articles/360001685039-How-to-delete-checkpoints-using-Hyper-V

    Furthermore, if you unable to view the checkpoints from the hyper V manager, we may merge the checkpoint files manually. In edit disks, find the avhdx file, and merge to the parent disk:

  • It looks like you have several snapshots taken for the VM.  The easiest way to get rid of the .avdx files is to delete snapshots and merge them into the current .vhdx.
