Server.MapPath() issue

Question

Hello All,

I have a very basic question. I was trying to export my CR file to PDF for that i used

string repFilePath = Server.MapPath("RadTechPublicReport.rpt");

It gave me an error say the path was not correct.

So i looked around and found that the it was missing a folder so then I replace the above code with

string repFilePath = Server.MapPath(@"Reports\RadTechPublicReport.rpt");

Now my question is why did MapPath not recognize Reports 

Please if any one can answer this question.
