Talking about snapshots all the time, I almost overlooked the free disk space (230GB) and the size of the virtual disk (200GB). With the free disk space it might be a better idea to clone the virtual disk rather than to consolidating all the snapshots.
To do this close VMware Workstation (or the VM's tab), create a new folder in the VM's directory (e.g. "vmdk-files") and move all .vmdk belonging to the first virtual disk to this folder (i.e. not the ones for the second disk "win7_x64_base-0.vmdk"). Then open a command prompt, go to the new "vmdk-files" folder and run:
"C:\Program Files (x86)\VMware\VMware Workstation\vmware-vdiskmanager.exe" -r win7_x64_base-000008.vmdk -t 1 ..\win7_x64_base.vmdk
After the clone is created, delete the VM's .vmsd file and edit the .vmx file (replace "win7_x64_base-000008.vmdk" with "win7_x64_base.vmdk").
If everything works as expected, you can delete the vmdk-files folder to free up a few hundred GB of disk space.
