Hi,
I’ve tried a couple of things, and can’t reproduce the behaviour with a new database.
It also seems like the behaviour in my existing database only happens with groups containing at least one file created (in Finder) in 2023 or before. Groups containing only newer files seem safe.
Furthermore, after one of the groups with older files is moved around, leaving behind an empty folder, any further refiling of the group is safe (i.e., no additional empty folders).
Kind regards,
Bram Adams
PS: I created my indexed databases in December 2023. The indexed folders were only manipulated by DT3.
