I didn’t realise you could do that on the web interface.
I’ve seen the feature in the API but I didn’t realise that people were using it!
There is no original location - it is all about the Object ID with google drive.
This is effectively the same as hard links on a unix filing system, with the inode taking the place of the Object ID.
rclone doesn’t deal with hard links (in general it is quite hard) so I can’t think of an easy way of getting rclone to help with this other than with some major re-architecting.
It would be possible to hardlink all the identical copies back together again at the end with a bit of scripting - maybe there is a script out there which can help with that?
