Is painter updating shelf files? Causing problems with incremental backup.

Painter 2019.1.3

I'm performing an incremental backup of my system, and noticed that my Substance Shelf files are all dated yesterday.
Only Shelf files are affected.
All I did yesterday was open Painter to find what version I have and then close it.

Is painter 'touching' or updating the shelf just because I run it?

This isn't the first time I've found the shelf files are all different to ones in backup for no apparent reason, and it's a nuisance when I'm trying to create incremental backups.

Thanks,
Epi

Yes, Substance Painter can edit some shelf resources when it needs to update some of their metadatas. Some newer updates can trigger that update. You should backup your assets before running Substance Painter.
