A replicated file is something like a link. So expiring replicants as regular files seems reasonable since the target file system might not support links, and even if it does, is not clear if you’d prefer you or hard ones.
Unrelated: i find it quite tedious to follow your every step in your experimentations detailed out in the forum. Maybe you could consider to post a single text after your trials with some concise (!) description of the issues you found?
What I try takes time, and while waiting, I was posting - which was not a good idea.
Sorry for that!
I have the impression, that the situation changed after time - even after the messages in box disappeared.
Right now, I see 5 videos again in the exported database!
So maybe all of that was just because the database is the largest of my databases and DT still does “something” even after stopping notifications.
It should better always indicate wether it is doing something or not.
I will only write again, if I can find something of substance!
P.S.
I manually checked for a new DT version and upgraded - DT did not notify me!
But it the same earlier … strange
