Shared Files from one Gdrive to my Gdrive using RClone

I know in Gdrive you cannot copy Shared files (unless someone knows). What I am trying to do is get the files being shared to me to my Gdrive without downloading to my computer and then uploading them to my Gdrive. However I did find a way within RClone to do it. Select the file or folder you want and select the button Download. A window pops up and you already have the source filled in. The destination you can put “Google:” and then hit run. Sometimes it works and sometimes it doesn’t.

What I want to know is why it works some and sometimes it doesn’t. It is the easiest and quickest way I have found to do this. Does anyone know the answer?

Nevermind this is for Rclone Browser
