ASP.NET Files are gone!!!

Hi everyone, new i am facing a big problem with fining the files of ASP.NET project,from two days all files that relate with asp.net were present but now everything is gone, like WebForm1.aspx , Web.config , Assembly ...
But when i open the Visual Studio.Net IDE all these Files are present,and when i go to the folder which i saved my project there is only one file which is solution file,so what should i do with this problem ,coz sometime i need to edit just the WebForm.aspx file

Visual Studio automatically places all ASP.Net project related files in [drive]:\inetpub\wwwroot\[Project name] folder
