Does retropie only copy new games from usb stick?

[guythp]

Sorry for this simple question, but I have a usb with the games I want already on but wanted to add a couple more to one or two game folders - I'm thinking the answer is no, but before I duplicate a load of games on my pi I just wondered if anyone could confirm; Does retropie only copy new files from usb or would it copy everything across (potentially leading to a lot of duplicates)?

I don't want to delete the contents of the USB unnecessarily before I do and it's only to add a couple of games to two systems.

Apologies again for such a basic question (I have read into the basics and searched for this topic but I couldn't see it come up) but I hope someone can help.

thanks in advance,

Guy
