Are you only browsing this site locally, or are you browsing it from a remote machine?
If you browser it from a remote machine, it won't work because the link "c:\myfile.pdf" refers to the c:\ drive on the webserver, which isn't accessible from your remote machine. In fact, it will cause your remote machine to look for "myfile.pdf" on its local c:\ drive. If you want to serve files in this manner, (i.e. server any file from your webserver to a remote client) then you need to load the file into a stream and send the stream to the client.
