I haven’t tried the beta, I’m not sure how that would work with rclone-browser. What I’m trying to do is move files from my local physical machine, to an external hdd connected to my router (NAS). They are ‘local’ but connected by network.
Interestingly enough I tried the Unison program which worked after I enabled the “is FAT” setting (even though the filesystem is NFTS). I’ll probably stick with rclone or Unison for now. ¯_(ツ)_/¯
