VMware Workstation is a virtual machine software suite for x86 and x86-64 computers from VMware, a division of EMC Corporation. This software suite allows users to set up multiple x86 and x86-64 virtual computers and to use one or more of these virtual machines simultaneously with the hosting operating system. Each virtual machine instance can execute its own guest operating system, such as Windows, Linux, BSD variants, or others. In simple terms, VMware Workstation allows one physical machine to run multiple operating systems simultaneously. Other VMware products help manage or migrate VMware virtual machines across multiple host machines.

Useful tips to resize a partition in VMware

Note: For any unexpected errors, MAKE SURE YOU HAVE A GOOD BACKUP!

Method One: Using the VDiskManager:

  • Turn off the virtual machine;
  • Commit/remove all the snapshots first! (I forgot to mention this, thanks JimO). Or make a Full Clone if you use Link Clones.
  • Open a Command Prompt and go to: C:\Program Files\VMWare\VMWare Server or C:\Program Files\VMware\VMware Workstation or for 64-bit C:\Program Files (x86)\VMWare\VMWare Server or C:\Program Files (x86)\VMware\VMware Workstation
  • Run this command to expand the virtual disk: vmware-vdiskmanager -x 12GB "My harddisk.vmdk" (in this case, 12 GB will be the new size). The file name can contain spaces because of the double quotes.

Note: Because this only expands the disk and not the partition, you'll need to resize the partition table as well. This can be done by freeware 'Partition Wizard Home', but also with 'diskpart.exe', a built-in tool of Windows.

Method Two: Using VMWare Converter

  • Turn off the virtual machine;
  • Start the VMWare Converter application;
  • Open the Convert Machine wizard;
  • Select 'standalone virtual machine' as the source and destination system;
  • Choose 'Select volumes and resize to save or add space';
  • Enter a new size and voilá, you're done!

Some say that the expand process is slow and that VMWare Tools might need to be reinstalled. A disadvantage is that Converter will create a new (many GB) copy of your VM.

Instructions for Windows Vista, 7 and 2008R2, then you can try diskpart command. Here is a tutorial: step by step instruction to extend partition with diskpart command

If your VM runs Windows 2000, XP, Server 2003 or Server 2003 R2 If your resized virtual disk is bootable, you cannot use diskpart from the virtual machine itself. Use a 3rd party tool or use another virtual machine.
