What is the use of Temporary ASP.NET Files Folder?

Question

Hi sir,
        Tell me the use of Temporary ASP.NET Files. I have more than 2GB space occupied in that. Can i delete all the files in that folder. If i delete all the files in that folder, it affects the visual studio 2010 software installed in the machine.

[Note: My query is "If i delete all the files in the below path, is it affects my visual studio, my C:\ drive is getting full, it's more than 2GB ]


C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files


Kindly give me the solution for this problem.
