Oh no worries, yeah that works like gitignore, I’m talking more like how Nextcloud and Dropbox let you like, have a list of folders and checkboxes where you can be like “this machine doesn’t need my family photo collection synced to it” kinda thing. Which to my knowledge syncthing doesn’t have.
Don't apologize tho! I appreciate the help!
You can achieve this by having multiple sync folders instead of one folder with everything. Then you can configure exactly what you sync where.
