hi Kamal,
i would question whether asp.net is the best choice of technology for what
you want to do. i found it difficult to understand your post, but i will
make the following suggestions anyway:
remember that Asp.Net will never give you access to a client file system
(except cookies of course), because it is being browsed over the generally
unsecure internet. your only option with Asp.Net is for the client to upload
a file to your web server, via the FileUpload control. alternatively the
client can download a file from the server.
how are your clients distributed? you say you want them to have some
software installed, which software? if you know how your clients are, just
get them to install an FTP server on their computer, or even better, get
them to sign up for a free FolderShare account, and share the computers in
the same FolderShare account. this will allow you to search the entire file
system via the FolderShare website, and it handles the downloading of the
file.
you could also use Windows XP remote assistance:

beyond that, you'll have to give a more detailed description of how and why
you intend to access a client file system via a web browser (it doesn't make
much sense to me).
hope this helps
