Using VMWare Workstation 10 in conjunction with Rockwell RSLogix 5000. Have installed the rockwell software and windows 7 on the VM. Specified a 40GB hard disk size. Software runs fine but the actual size of the VM is 115GB. No snapshots, have tried cleaning the disk, compacting, but nothing helps. There is a 97GB virtual disk file in the folder that cannot be explained. The rest of the virtual disks are the expected approx 2GB. Contacted Rockwell as this is a common configuration to have this software running on a virtual machine and they have had no reports of this symptom. Issue with the VMware.
