SUMMARY Using Synchronise Folders on "similar" source/destinations where there are a subset of subfolders selected on one side, it only works correctly if "nothing" is selected (or actually currently positioned, doesn't matter if selected) on the destination side. If the "cursor" is not on an "empty" line - that is - not (usually) on the [..] entry but on anything else, that entry will be included in the comparison. STEPS TO REPRODUCE 1. Select some subfolders/entries in the source 2. (Mistakenly) leave an entry focused (other than ..) in the destination which is not part of the "source" selection (happens more often than you think) 3. Choose to Synchronise Folders OBSERVED RESULT The "additional" (not selected but focussed) entry from the destination is included in the sync. EXPECTED RESULT The "additional" (not selected but focussed) entry from the destination should not be included in the sync.
