If RAR program was installed on the server, so Asp.net can call RAR to realize a file to compress compress with solution.
What want an attention nevertheless is, because Web program cannot call the program that the client carries directly (unless use ActiveX, activeX is discarded almost) , if want to come true,let an user compress this locality file with webpage solution so the RAR that uploads the file to the server to call a server to go up again only is compressed, the RAR document that wants solution to compress this locality with manage can upload the file to the server solution pressing is taken again.
The article tells the catalog solution that how carries in the server to compress a file!
