This sounds like such a simple thing but I cannot figure out how to choose specific folders to automatically backup. When I get to the backup folder selection menu in the dropbox app I have half a dozen high level choices like "Desktop", "Downloads", and "Videos" to choose from but I don't want to automatically backup any of those, I want to backup specific folders like "C:\cygwin64\home\foo\bar" - how do I tell the app to do that? I'm on a Windows 11 PC.
