My wife plugged in a thumb drive and was dragging a folder out of it to place in her iPhoto library and it completely disappeared. No puff of smoke or anything. I've searched everywhere on the mac for it and it's not there. It is also gone from the original thumb drive. What the heck happened? It's not in the trash, not in any folder. I've searched with Quicksilver, Spotlight, the 'Today' folder, the 'All Images' folder, and nothing. Where could it have gone? We have an iMac. Thanks for any help.
