Question / Problem
After scanning a share with TreeSize Professional I want to compare this scan with existing snapshots. After clicking the "Compare with Snapshot" button I retrieve an empty list of snapshots and the message "No snapshots available for this scan".
Answer / Solution
Either no snapshots are existing or not all necessary services are running on the destination system.
You can verify the latter one as follows: right-click on the destination directory in Windows Explorer, open the properties page and select the "Previous Versions" tab.
If no snapshots are listed there, TreeSize itself cannot display any entries. If you see entries there, not all services required for the comparison were running.
These services have now been started implicitly by opening the "Previous Versions" dialog. If you execute "Compare with snapshot" again, you should see the correct results.
