How to Remove a VM…and Bring It Back Again

The virtual machine (VM) files in Parallels Desktop® for Mac can be quite large—I have several that are over 100 GB. So if you’re not using a VM anymore (or just rarely use it), you can get back a lot of space on your Mac® by deleting it, or at least moving it to an external drive. In this short blog post, I’ll show you how to remove a VM—and how to bring it back again.

Removing a VM

Removing a VM is most easily done from the Control Center window in Parallels Desktop. Just right-click on the entry for the VM you want to remove, and you’ll get a pop-up menu with the Remove command. (See Figure 1.).

When you choose the Remove command, you’ll get the dialog shown in Figure 2.

If you want to completely get rid of the VM, use the Move to Trash button. (Don’t forget to empty the trash to recover all that space on your Mac.) However, if you might want to use the VM again, use the Keep Files button.

Store the VM

Storing the VM on an external dive is easy; there’s only one file to put on the external drive, but it might be a rather large file. The .pvm file stores all the VM’s information: Windows itself, all the Windows applications you have installed, all the data files you’ve created, and all the VM settings (the amount of RAM you want this VM to have, the number of CPUs, the network settings, and more). Just move this single file to your external drive, as shown in Figure 3.

Restore the VM

Restoring a saved VM is also easy. First move the VM back to the place on your Mac where your VMs are located. Then just use the Open button on the Installation Assistant window to restore your VM to the Control Center list (See Figure 4.).

If you see a dialog about duplicate MAC addresses (Figure 5), just click the Create new button.

I hope this blog post helps you manage VM files and save space on your Mac.
