I guess I'm not tracking. I put all my source folders in my Documents folder on the Mac, and check the checkbox to have that sync to iCloud. It works quite well.

I also do a bunch of video work with Da Vinci Resolve, and those project files are in the same folder. I don't keep the clips there, those are on an external disc, but that's just because I haven't gone from the two terabyte iCloud plan to the six terabyte plan.
