The scenario

“I've searched far and wide (Page 1 of Google) and all I could find was how to 'steal' files from someone’s computer upon inserting the USB; this is not what I'm asking for, I'm very against it.

I want to give my friend some files (Non-workshop addons for GMod) but she's not too tech savvy, and I figured, instead of taking her through the boring steps, I can make it automatically move the files upon inserting the flash drive or upon double clicking the batch file (I don't mind which).

Does anybody know how one would achieve this? Or how the batch file would be written?”

In this situation, a USB hidden copier will help a lot.
