Others Files won't delete

[Abphotog14]

I have a Nokia Lumia 1520 up till today my phone storage was fine then all of a sudden this "Other File" has 8.30 GBs of my memory gone!!!! I have an sd card an I have tried everything to delete these files from this "Other" when I click on it it says can't delete from phone try plugging to computer I have done that there is nothing that I can delete with my phone hooked to the computer because everything is on my sd memory card. What and how can I get this deleted it's driving me crazy.

Thanks in advance

Try deleting your temp files it might get rid of the other storage.
