Can we ZIP/Unzip files larger than 4GB using .Net 4.5 libraries

With .NET 4.5 you can now unzip files using the .NET framework:

using System;
using System.IO;

namespace ConsoleApplication
{
  class Program
  {
    static void Main(string[] args)
    {
      string startPath = @"c:\example\start";
      string zipPath = @"c:\example\result.zip";
      string extractPath = @"c:\example\extract";

      System.IO.Compression.ZipFile.CreateFromDirectory(startPath, zipPath);
      System.IO.Compression.ZipFile.ExtractToDirectory(zipPath, extractPath);
    }
  }
}

The above code was taken directly from Microsoft's documentation: http://msdn.microsoft.com/en-us/library/ms404280(v=vs.110).aspx

ZipFile is contained in the assembly System.IO.Compression.FileSystem. (Thanks nateirvin...see comment below)

DotNetZip example:

int segmentsCreated ;
using (ZipFile zip = new ZipFile())
{
  zip.UseUnicode= true;  // utf-8
  zip.AddDirectory(@"MyDocuments\ProjectX");
  zip.Comment = "This zip was created at " + System.DateTime.Now.ToString("G") ;
  zip.MaxOutputSegmentSize = 100*1024 ; // 100k segments
  zip.Save("MyFiles.zip");

  segmentsCreated = zip.NumberOfSegmentsForMostRecentSave ;
}

if segmentsCreated comes back as 5, then you have the following files, each not more than 100kb in size.

• MyFiles.zip
• MyFiles.z01
• MyFiles.z02
• MyFiles.z03
• MyFiles.z04

Edited To Note: DotNetZip used to live at Codeplex. Codeplex has been shut down. The old archive is still [available at Codeplex][1]. It looks like the code has migrated to Github:

• https://github.com/DinoChiesa/DotNetZip. Looks to be the original author's repo.
• https://github.com/haf/DotNetZip.Semverd. This looks to be the currently maintained version. It's also packaged up an available via Nuget at https://www.nuget.org/packages/DotNetZip/
