Is that not how it works? I could have sworn I had it working that way the last time I used it in 2017. Had it rigged up as the location for Da Vinci Resolve database saves and also as a backup location for an Avid project that automatically copied to that folder every day. Wasn't a fan of OneDrive as I had dropbox personally and didn't want another cloud service where I stored all my data as one was probably bad enough, however the production I was working on had no IT infrastructure and no money and the computer we rented for the production for some reason seemed to offer oneDrive for free with the machine. (Maybe it was something to do with the 365 subscription it had?). On that basis since it was already there I used it and it actually ended up saving our asses later on after some other backup procedures didn't end up being followed as they should have and the piece of shit rental machine totally and catastrophically broke. Still haven't used it since, but I was pretty happy with it at the time and was only able to do all that because it was indeed a regular folder location on the machine that happened to sync with the cloud.
