On my S5, I had several gigs of miscellaneous files, and it turned out that this was data from the Google Play Movers & TV app and data from the Comixology Comics app. In both cases, looking at the application through the application manager said the data for both was on the SD card (and the settings inside Play Movies and TV said to use the SD card for storage) . However my SD card used space was significantly less than what either app said it was using. When I cleared the data for the two apps, that dropped my Miscellaneous space used from 5gigs down to 434mb. (without changing my SD cards used space at all)
