Caution: This article assumes familiarity with how snapshots work.
The most likely reason for running out of disk space (if you have not recently saved any large files to your computer) is that one or more snapshots have grown too large. If this occurs, you have three options:
1. Shut down the virtual machine
2. Go to the option 'VM' > Snapshot Manager
3. Select each snapshot and delete them from left-to-right
This consolidates all of your snapshots into your main disk. If you do not have enough disk space to do this, use option 2.
If you cannot see any or all of your snapshots in the Snapshot Manager, and you do not have sufficient disk space for Fusion to consolidate them, you must consolidate your snapshots manually.
To consolidate data from the snapshot(s) and from the main virtual disk, use the command-line utility vmware-vdiskmanager to create a new virtual disk.
1. Shut down the virtual machine.
2. Quit VMware Workstation.
3. Open Windows Explorer and locate the virtual machine.
4. Open Command Prompt as an Administrator.
5. Copy and paste this text into Command Prompt:
"C:\Program Files (x86)\VMware\VMware Workstation\vmware-vdiskmanager.exe" -r
6. Give a space.
7. From your virtual machine folder, drag the current virtual disk file into the Command Prompt window.
8. Give a space
9. Copy and paste this text into Command Prompt:
-t 0
10. Give a space
11. Type the new location for the virtual disk, followed by a forward slash ( /), and enter a new file name (for example : NewDisk.vmdk).
Example:
"C:\Users\username\Desktop\NewDisk.vmdk"
12. The command will look similar to this:
"C:\Program Files (x86)\username\VMware Workstation\vmware-vdiskmanager.exe" -r "D:\Virtual Machines\Windows 7\Windows 7.vmdk" -t 0 "C:\Users\username\Desktop\NewDisk.vmdk"
13. Press Enter
14. A message that says Converting... followed by a percentage appears. The length of the process varies depending on the size of the virtual machine.
You may then create a new virtual machine based on this 'NewDisk.vmdk" file
After the snapshots have been consolidated, you need to use the new virtual disk. The easiest way to do this is to make a new virtual machine that uses the new virtual disk you have just created (which has all of the information from your old virtual disk and all of the snapshots). To make a new virtual machine that uses the new virtual disk, refer to Creating a Workstation virtual machine using existing VMDK virtual disks (2010196)
After powering on the new virtual machine, compare it with the old virtual machine and ensure that nothing is missing. If you see any files or folders missing, you may have neglected to re-enable Shared Folders or Mirrored Folders.
