Windows Explorer style custom control for web

[sri_san]

Hello,
I am trying to develop a aspx page which would have the
capability to upload images/media files(.mp3/.avi) and have a
hierarchial structure(like the windows explorer) displaying the list
of files,folders. This page could be used at multiple places. Hence,
need to communicate between the parent page and this page(assuming this
is going to be a popup window). Unable to figure out where to start
from. Any pointers with an outline or similar kind of control out there
would be great!!

Thanks in advance,
Sam.
