I need to find a file path to attach multiple files in an application to send to others

In my application I need to send mail to others and also I want to add some files. But I cannot get this file attachment in mozilla firefox. If I give the full path, it works fine, but in the browser, it doesn't accept the full path. How can I get the path? Is it possible or any other solution to get the file path. I hope someone can help me.

Thanks in advance.

Here is my complete code ::
