So i'm checking my sd card for an app i just downloaded and i notice i have a ridiculous amount of free space, turns out everything got screwed. Check it out, looks like this:
I'm not exactly sure but it looks like your card got corrupted somehow. At least you still have your important stuff. Try formatting your card and make sure you put the important stuff from sd card to your comp then format it.

It's possible that this could be malware... or something else.
Might help you eliminate a few causes off the list.
