I transferred some picture files over to a micro sd card. After doing this some of the files show up and some have a thumbnail with a lightning bolt through it. When I try to open the file on the computer it says the file has been corrupted. Ive tried multiple different photo viewing apps as well as sd card formatting apps. Nothing seems to work.

Once corrupted it's a wrap. You're asking an app to fill in damaged information. Your only option is to check the source and be sure the data is good, and then attempting to transfer the items again.

One note, it shouldn't matter really how many files you attempted to transfer at once but because you did and up with corrupted data once, you may want to either transfer in smaller batches, and transfer with as little going on as possible. So not running an app in the background or while playing a game.
