# com.unity.sharp-zip-lib
`com.unity.sharp-zip-lib` is a package that wraps [SharpZipLib](https://github.com/icsharpcode/SharpZipLib) to be used inside Unity,
and provides various compression/uncompression utility functions.
Currently, this package uses [SharpZipLib v1.3.3](https://github.com/icsharpcode/SharpZipLib/releases/tag/v1.3.3).
Please refer to the [installation](Installation.md) page to install this package.
> 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](https://github.com/icsharpcode/SharpZipLib) APIs are available under `Unity.SharpZipLib` namespace. For example:
```csharp
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](https://github.com/icsharpcode/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:
```csharp
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);
}
```
## Supported Unity Versions
* Unity `2021.3.45` or higher.
