After migrating all documents from Old_Volume to New_Volume, we can still see a very large number of images still exit under the volume folders in windows folder structure.
We ran the Volume Consistency Utility and it comes back with "Total Images = 0".
Also the Statistics tab of the volume shows Documents = 0.
1. Statistics --> Statistics tab of Volume
2. Volume Path details
3. Volume Consistency Utility
4. Physical Files: Images still exist on Windows Drive under Old_Volume folder
Do you think it's safe to delete this Old volume from the windows system?
