I tried this, was not sure it worked as other websites had much more complex ways to do this but this worked amazingly and was so simple!

Hi KK, the easiest way to shrink a VMDK is probably to use VMware converter. This can be done in a few simple steps:

1) Install VMware Converter on the VM that you want to shrink the VMDK(s) of.
2) Run VMware Converter and select the options to 'import a machine' and then 'this local machine'.
3) Select the volumes you want to import and change 'maintain size' to 'type size' and specify your reduced VMDK size(s).
4) Complete the wizard to import the virtual machine
5) Shutdown the original VM and power on the newly imported VM (with the smaller VMDK(s)

What about to shrink the size of the virtual disk? When i iedit the settings to make it smaller it goes back to the original size. We are importing physical machines to the virtual environment and some disk are way too big....

Hi Dom, this is probably because
1- you cannot resize virtual disk if there are any snapshot of that VM;
2- you cannot resize IDE disk (IDE disk are used to install windows XP to avoid the SCSI driver installation).
Look at this post on VMware community

Hi - on my VM's (v.7 ESX4.0), in the disk provisioning section on the dard disk properties it's all greyed out - can't change the size?
why's that?

It worked! No shutdown required. But beware: when you just run"extpart", the program asks the drive letter. It is essential that you type the letter followed by ":", otherwise the error "Unable to connect to C or it does not exist" occurs.
