How can I move the Vmware virtual Hard Drive files?
Solution 1:
VMWare is a company not a product, presumably you mean a client-based product such as VMWare Server or Workstation? if so can you update your question?
Probably the most fool-proof way of doing this would be to remove the server from your list of VMs but don't choose the 'remove from disk' option. Then move the VM directory/files from C: to V:, then browse to the new directory and double-click the appropriate .vmx file. This should then either add the VM back into your list or start a wizard to do the same. Worst case scenario just choose 'add new VM' and choose the 'use existing virtual disk' option.
Solution 2:
I'm presuming you're talking about VMware Workstation -- just move the files where you want them, remove the virtual disks from the VM configuration (don't delete them), then add virtual disks, select the option to add existing virtual disks, then locate your .vmdk files.
Note that your virtual disk actually consists of the .vmdk, which is a metadata descriptor, and the -flat.vmdk, which actually contains the data. You'll want to move both of these to the same location.
