I have read about how, supposedly, one can block trying to sync MacOS’ icon files from syncing because Windows can’t make sense of them using patterns like:
!Icon[a-z0-9_-]
(?d)Icon?
Icon?
I have these patterns on both sides.
The icon file continues to try to sync. I even reset the Mac icon, set the exclusions again, and updated.
Stating the obvious maybe, but have you deleted the files on the Windows side? Ignoring them on the MacOS source does not mean they will get deleted automatically on any remote, once synced.
TL;DR - Folder defaults aren’t applied retroactively. You have to add excludes to anything created before the folder default is set.
The issue was that I learned about the “icon fight” AFTER I created a sync pair. Then, I went to Actions → Settings → Edit Folder Defaults. Saved.
I thought that would apply to everything, including retroactively. It did not.
I manually applied the excludes on both sides to the sync pair I created initially. Indeed, fixing this on the Mac also “resolved” the issue on the OTHER Windows machine that was trying to sync this Windows-unfriendly file without having to change anything on said Windows machine as the Mac was no longer trying to push it.
