Apologies for the confusing sentence.
First copy command creates duplicate file in the destination. so the googledrive and localfolder are not identical.
The second copy command is again recreating the moved file by copying it from the localfolder to googledrive. Now the googledrive and localfolder are identical but with duplicate files.
Logically speaking this the expected behavior of the copy operation, but I was trying to understand the answer
"the copy command shouldn't be making duplicate files"
How safe is bisync? I mean is it as reliable as the native mirroring done by googledrive apps on windows?
Thank you so much for your reply.
