Upload and delete server´s videos from client with webservices (C#)

[C# Programming]

Hi! I would like know how can I upload and delete video files saved in server using an aplication from client with webservices.
I was reading that I can use the class HttpFileCollection, class Uploader: IHttpHandler with the method ProcessRequest( HttpContext context ) or ftp.
What do you think? Any suggestion?
Thanks a lot. http://www.barakasoft.com/script/Forums/Images/smiley_smile.gif
