You will need to provide a lot more information than this if you expect any useful suggestions.

I don't know about the ZIPPACKAGE. I'm using DotNetZip Library from CodePlex[^]. It is easy to use in C# or VB.NET and the examples are good.

For instance the follow code would unzip all files in a WinZip file (using the DotNetZip code)

VB

Imports Ionic.Zip

Private Sub UnzipFile(filename As String, targetFolder As String, password As String)
    Using zip As ZipFile = ZipFile.Read(filename)
        If String.IsNullOrEmpty(password) Then
            zip.Password = password
        End If

        zip.ExtractAll(targetFolder)
    End Using
End Sub

Thanks :)

I have read it partally and it looks very promissing. I'm definitely going to test the demo code. Using Visual Studio components do have my preference over third party components.
