How do I ignore files from being synced with Obsidian-Sync?

What I’m trying to do

I need to ignore some files from being synced. Not folders, files. There is the possibility to ignore files from Search, Graph, etc. but I really need to ignore some files from being synced across devices.

Is this even possible or should this be a feature request?

It’s not possible at the moment.

Existing feature request: Obsidian Sync Exclude single file

For what it’s worth, while you can’t exclude single files from synchro, you can exclude folders.
