Creating a Build

I am creating a build and logged in to the server and i am looking at the “ClonesOnly” folder

I see that a clone is deposited and then disappears.

With this am I correct that you make a clone for each file one at a time then add it to the zip and then remove it - kind of transactionally?

Could there be an option to make a clone of all files then zip up the entire directory, then remove the clones?

Can you tell me why?
