        No, it's not necessary to new, you can create the ROM transfer folder on an existing USB drive without clearing or deleting the folders you already have.

            Please more info about your setup as, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

            How is the flash drive formatted ? If Linux cannot read/write to it, it won't work.

                  @persephale It's the same as flashing a sdcard, if your Pi supports booting from USB. Pi4 should have this by default, for the Pi3 you still need a sdcard in order to boot RaspiOS and enable USB booting. See https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#usb-mass-storage-boot for more details on Pi USB boot support.
