Yes, if there is a link to a site that will show what you are trying to explain, then feel free.

Bottom line is, if you are trying to access files on the client machine, then this work has to be done on the client side, i.e. using an HTML input control. You can't access files on the client file system directly from your server side code, the file first has to be chosen on the client, uploaded to the server, and then worked on.
