Hello, I am a newbie here and am in need of some assistance. While doing business with a client, I had to plug his USB into my computer to transfer some footage. I'm not sure if he knew, but I had my OS set to display all "hidden" files. This is when I saw 3 "hidden" files on his usb; an "EFI" , a "live" and a "install". I transfered the files from his USB over to my computer and have begun inspecting them. I understand that they may be some sort of Linkux bootable, with possibly Clonezilla, and some other stuff that I am unaware of. I could use some help analyzing the folders to determine what these folders are actually doing and whether or not their is some mal-intent on my clients side. I am slightly suspect that he may be trying to snoop my hard drive.
