Hi,

there are some open source zip libraries but their compression rate is to low. I can advise you to use pocketrar. here is the place to download it. it is freeware:

http://www.rarlab.com/rar/pocketrar393.exe

the rar file will reside somewhere under \\program files\pocket rar\rar.exe
here is an example on how to extract an archive. more information you can find on winrar help file for command line parameters:


string PKatalog = "Storage Card\\AronDB\\MyFile.txt";
string PSource = "\"\\Storage Card\\MyArchive.RAR\"";
string PDestination = "\"\\Storage Card\\\"";
string PRarPlace = "\\Program Files\\Pocket RAR\\rar.exe";
string PCommand = "e -idp -o+";

System.Diagnostics.ProcessStartInfo pi = new System.Diagnostics.ProcessStartInfo(
                PRarPlace,
                PCommand + " " + PSource + " " + PDestination
            );
 
            System.Diagnostics.Process p = new System.Diagnostics.Process();
            p.StartInfo = pi;

            p.Start();
             p.WaitForExit();

There is "Discussions" page in that project with all answers. For example:

Or simply delete it if it does not want to work for you - it's an open source project, choose another one.
