Hello all, new to Android and this forum.

I purchased my new S3 16G about a month ago.
When I go to Settings> Storage, it says I have just under 4G in "Miscellaneous files."
I tap it and it only gives me a couple MB i can delete.

I have gone through the phone searching for files I can delete but nothing seems to make the number decrease and I can't think of anything that would take up that much space.

What and where are these mysterious files and can I delete them. I don't want a quarter of my storage taken up by these mystery files.

I appreciate any help on the subject.
