My Nokia 822 is duplicating videos, music & some photos. All are loaded to the SD card. I have 3+ duplicates of the same music & videos, duplicating more every day! It does not seem to take up any more data space, but if you delete one of the copies, the others will not play! I have never seen anything like this before... any ideas?

Skydrive is turned off, all items were loaded to the card by hooking up the cable to W7 computer, drag & drop. Brand new Sandisk 64g class 10 card formatted to phone. Everything plays fine, but just keeps multiplying!
