Easy way to transfer tons of old photos to flash drive

That's a HUGE OBTW !

Gotta scan them to .jpeg either one by one, or multiple pix on a flatbed scanner. I'm looking at something other than my office scanner to do the same.

Only problem (that I felt to mention), the photos or are on hardcopy, not in desktop. Some taken back prior to digital cameras.

Simply open the flash drive on the desktop and slide whatever pix you have onto it. Or likewise slide the folder where they are stored onto the drive
Make sure its big enough too
