Ok, I need to tap into the collective expertise here. I know I can buy a 10-port USB hub. If I do, could I put 10 flashdrives into it and write a file to all 10 simultaneously? Or would I have to do the click-drag for each one sequentially? (Running Windows on PCs here.) We have about 1,000 flashdrives that we need to load with a .pdf-format marketing presentation and don't want to load them individually. Thanks!
