The version numbering of this package itself and the version of SharpZipLib used in the package may look similar, but they are not related.

How to Use

• All SharpZipLib APIs are available under Unity.SharpZipLib namespace. For example:

    using System.IO;
    using Unity.SharpZipLib.GZip;
  
    ...
  
    public void UseSharpZipLibAPIs() {
        MemoryStream ms = new MemoryStream();
        GZipOutputStream outStream = new GZipOutputStream(ms);
        ...
    }
  

  Please refer to the API documentation of the SharpZipLib version used in this package for more details.

• In addition, com.unity.sharp-zip-lib also provides additional utility APIs:

  • ZipUtility.CompressFolderToZip(): Creates a zip file on disk containing the contents of the nominated folder.
  • ZipUtility.UncompressFromZip(): Uncompress the contents of a zip file into the specified folder.

  As an example:

  static void CompressAndUncompress() {
      //Compress
      string folderToCompress = "Assets";
      string zipPath = Path.Combine(Application.temporaryCachePath, "UnityAssets.zip");
      ZipUtility.CompressFolderToZip(zipPath,null, folderToCompress);
      Debug.Log($"{folderToCompress} folder compressed to: " + zipPath);
  
      //Uncompress
      string extractPath = Path.Combine(Application.temporaryCachePath, "UnityAssetsExtracted");
      ZipUtility.UncompressFromZip(zipPath, null, extractPath);
      Debug.Log($"Uncompressed to: " + extractPath);
  }
