iPhone5 Problem when I connect with my PC.

Hello everyone !

I have iPhone 5. When connect it with my PC, I checked the iTunes and I see that there is "Others" part and it is indicted with orange. It is about 1GB and I want to delete it. Because it is different from apps and musics. I used my phone 1 month. But I want to delete the others part. And I checked this problem on the internet. One of the guy says that it is 9 GB on my iPhone !!

I don't want to restore my iPhone ! Please tell the solution. I turned crazy !!!
