Browse server from Admin

please i need to know how to Browse server from my Admin page.
i made an admin page with username and password…

i want the administrator to browse the server to choose an uploaded file to be shown in the front end page

SO i need to know how to browse server and choose file from it like the tag

<input type="file" />

but browsing the server

You can’t.

Instead, use a serverside programming language to show a list of files.
