I bought a 16GB flash drive and put a lot of videos from trips, a lot of pictures, and a lot of music. When i was pretty much finished putting every thing on there, it said i had to format it.when i ever i connect it now that same thing shows up about formatting. and since i saved every thing on there i had deleted my things from the computer. if i format it, it says it will delete every thing. so what can i do to keep my files? Or get them back??
