Update zip file based on other zip file C#

So i have a zip file in a directory. This zip file contains different kind of files. When a user clicks on a button in my WPF application, the zip file needs to be updated.

It needs to check files from another zip file in another directory. If a file doesnt excist in the first zip file, it needs to copy that file from the other zip file to the new zip file.

i used the Ionic zip methode for this.

So far i just used the file.copy overwrite = true code. But when the zip file is 1gb+ it is taking very long because it just replaced the zip file.

does someone know how i can resolve this?

Greetings Thomas

UPDATE: this is the code i got so far:

private void getlocaldata()
        {

            string admindata = @"\\networklocation\test.zip";  
            string localPath = @"C:\finaldata\test.zip";   

            File.Copy(admindata, localPath, true);

        }

You can use the DotNetZip library.

Check the file in the zip :

zip["Readme.txt"] = null;

But anyway you must compress files again for changing zips password. You can find examples for that here.
