    I am trying to delete a couple of snapshots in my Windows 8.1 installation and keep getting the error PRL_ERR_DISK OPERATION_NOT_ALLOWED.

    Any help would be appreciated!
    Thanks!

    Hi @ChristianE2, we recommend you to merge those snapshots as suggested in this article. Because when you delete an intermediate snapshot, the information it contains is merged into the next snapshot.

    Thank you! However, I get an error message when I follow these instructions. It simply says "Unable to merge snapshots."

    P.S.: I really don't care about preserving any of the snapshots. I never meant to create the intermediate snapshot like that. It somehow happened when I upgraded Windows to Windows 10 and then went back to a previous snapshot to undo the upgrade. I am just trying to reclaim some disk space.

  9. Hello,
    please make a backup copy of your VM before performing the steps below.
    1. Locate your Virtual machine in Finder

    2. Right click on the *.pvm file of your virtual machine -> choose Show Package Contents

    3. In Mac OS X, go to Applications > Utilities and launch Terminal. Type the following but do not execute:

      prl_disk_tool merge --hdd

    4. Drag the *.hdd file into Terminal and drop it right next to "prl_disk_tool merge --hdd ". In Terminal you will see something like this:

      prl_disk_tool merge --hdd /Users/Username/Documents/Parallels/Windows\ 7.pvm/Windows\ 7-0.hdd

      Note: There should be a space between '--hdd' and 'Users/Username...'

    5. Press Enter/Return key to run the command and merge the snapshots.

    6. In the same directory (inside Virtual Machine's bundle) delete Snapshots.xml file
