If I find a 64 GB USB drive, you damn right I’ll plug it in.
If I cant ID the owner, finder’s keepers!
My PC doesn’t run anything off of one automatically, and I’m not going to click on .exe, .bat, or HTML files as a matter of years old habit.
A brand new 64GB USB3.0 flash drive will cost you less than twenty bucks.
I've read about cases where these devices have been hacked to identify themselves as USB keyboards, and then they start sending keystrokes automatically when they're plugged in.
