Getting "Access Denied" while trying to acccess file from Physical location

Hi All,

I want to display the file in Sharepoint Modal Dialog window thru programatically. If I store the file in document library and pass the logical location in query string(http:\\<serverurl>\Source="/<Doc lib>/<filename>").It works fine.

But If I kept the file in local drive (e.g D:\sample.doc) and pass the physical location in query string such as http:\\<serverurl>\Source=D:\sample.doc"".I'm getting "Access Denied" error.

Any help will be much appreciated!!!
