On my Galaxy Note 4, how do I find out what the miscellaneous files contain?

[AC Question]

galaxy note 4 - lack of storage space miscellaneous files 12GB!

My miscellaneous files are 12 GB!! When I tap on it to interrogate it there is a listing only of 46 files all of which are about 600 KB - any ideas on how to find out what these files are?

Ive looked in my files and found all is well there as these downloads I store to my sd ...

All help much appreciated
