PowerPlay Zipper is an implementation of Lightning-Fast Zip file compression/decompression library on .NET. Simple word for strategy: Maximize multi-core parallel file compression/decompression.

• 3x and over faster unzipping execution than SharpZipLib.FastZip / System.IO.Compression.ZipFile.

Yes, we can easy replace PowerPlay Zipper from another zip manipulation library.

// Install NuGet "PowerPlayZipper" package.
using PowerPlayZipper;

public async Task YourUnzipTaskWithVeryLargeZipFile(
    string zipFilePath, string storeDirectoryPath)
{
    Unzipper unzipper = new Unzipper();
    ProcessedResults result = await unzipper.UnzipAsync(
        zipFilePath, storeDirectoryPath);

    Console.WriteLine(result);
}

// Install NuGet "PowerPlayZipper" package.
using PowerPlayZipper;

public async Task YourZipTaskWithManyFiles(
    string zipFilePath, string targetDirectoryPath)
{
    Zipper zipper = new Zipper();
    ProcessedResults result = await zipper.ZipAsync(
        zipFilePath, targetDirectoryPath);

    Console.WriteLine(result);
}

# Install ppzip command from NuGet.

• Ubuntu 20.04: 3.1x faster than System.IO.Compression.
• Windows 10 19043: 2.2x faster than SharpZipLib.

• Ubuntu 20.04: 2.3x faster than System.IO.Compression.
• Windows 10 19043: 2.5x faster than System.IO.Compression.

PowerPlay Zipper is made with neutral/independent any reference. See NuGet dependency list.

• .NET 5.0 or higher.
• .NET Core 3.1, 3.0, 2.1, 2.0 and 1.0.
• .NET Standard 2.1, 2.0, 1.6 and 1.3.
  • netstandard13 and netstandard16 referred System.Threading.Thread 4.0.0.
• .NET Framework 4.8, 4.6.2, 4.5, 4.0, 3.5 and 2.0.
  • net40 referred Microsoft.Bcl.Async 1.0.168.

If you use ICSharpCode.SharpZipLib.FastZip or System.IO.Compression.ZipFile, PowerPlay Zipper produces similar interface for FastZip and ZipFile classes.

// use PowerPlayZipper migration layer.
using PowerPlayZipper.Migration;
//using ICSharpCode.SharpZipLib.Zip;

var fastZip = new FastZip();
fastZip.ExtractZip("zipfile.zip", "C:\output", "");

// use PowerPlayZipper migration layer.
using PowerPlayZipper.Migration;
//using System.IO.Compression;

ZipFile.ExtractToDirectory("zipfile.zip", "C:\output");

• Will not support these zip file features:
  • Only supported deflate compression algorithm, will not support any others.
  • Any encryption and decryption feature.
  • Continuous streaming unzip. PowerPlayZipper depends seekable file accessing.
  • Supported only synchronized interface between net20 and net35 platforms.

Under Apache v2.

• 0.0.51:
  • Enabled ability of long path names on Windows (.NET Framework/.NET Standard)
  • Completely separated accessor for file system manipulation by an interface IUnzipperTraits.
  • Added migration layer interfaces similar SharpZipLib.FastZip and System.IO.Compression.ZipFile.
  • Implemented generation 4 improvement with lock-free structure (WIP).
• 0.0.32:
  • Rewrite new generation 3 unzip code made faster to 3x (dotnet/docs).
• 0.0.29:
  • Added .NET CLI tool package named ppzip.
• 0.0.27:
  • Minor bug fixed.
• 0.0.12:
  • First NuGet package released.
