I just did a quick flight today and when I went to pull the memory card and look at it in my computer this is what it showed.
This is a DJI Phantom 3 Standard and using iPhone 6s.

the video files are ok. Memory card is a Sandisk Ultra PLUS 32GB
Just wondering if anyone knows what this might be. I tested the memory card and it passed.

i'd just format your card after you moved your files off

Yes, I agree. It looks like the card is corrupted, a format may fix it.

I did format it after that and it seems fine. Just wondering what the heck was going on and if anyone else had seen this.

Likely some of the free @DJI spyware included in every firmware and Go app update... ;-)

It seems the card was infected with some typical Trojan or virus when it was operated in PC.

Corrupted files can have many causes. Removing the card while it is still being written to is one common cause. Plugging the card into the Phantom while the Phantom is powered on could do it.  Bad sectors on the card .  Voltage spikes, magnets too close to the card. It is magnetic media ,  and subject to getting scrambled from a variety of sources. Just format it,  or,  if it has files you wish to recover,   run chkdsk.exe /f  from the command prompt. Best bet is to format it though.
