…anybody to do mass-scale automation must indeed use caution.
But you know better than most around here that we cannot give them scripts without knowing their files, etc.
My idea was a general starting point. That’s as far as free advice can go.
I’m not sure tools like Directory Opus can be of help, but maybe, if he’s on Windows. But even there he’d need some script and he may not get it on their forum, either.
Otherwise, he needs to learn some of the ropes and get the job done, in, say, 3-6 months time.
Anybody who uses Obsidian is recommended to learn some scripting, regular expressions, DataView queries etc.
Do you concur, my good sir?
