recently any files i either a) delete/move in bulk while holding the CTRL button or b) entire folders i delete, have been reappearing when my computer restarts after shutdown. the deletion shows up in my recycle bin or the destination i moved it to, but it's like another copy appears in its place. these have so far been .mp3 or .jpg files (i haven't tried it on any other kind). i've emptied the recycle bin and they still appear. what could be causing this?
