Package AppVeyor Codecov

Cube.FileSystem.SevenZip is a wrapper library of the 7-Zip via COM interface. The project also has an application for compressing or extracting archives, which name is CubeICE. Libraries and applications are available for .NET Framework 3.5, 4.5 or later. Note that some projects are licensed under the GNU LGPLv3 and the others under the Apache 2.0. See for more information.


You can install the library through the NuGet package. Add dependencies in your project file or select it from the NuGet packages UI on Visual Studio.

Examples for archiving files

A simple example for archiving files is as follows. Note that the statement "using Cube.FileSystem.SevenZip;" has been omitted in all samples.

// Set only what you need.
var files   = new[] { ".DS_Store", "Thumbs.db", "__MACOSX", "desktop.ini" };
var options = new CompressionOption
    CompressionLevel  = CompressionLevel.Ultra,
    CompressionMethod = CompressionMethod.Lzma,
    EncryptionMethod  = EncryptionMethod.Aes256,
    Password          = "password",
    Filter            = Filter.From(files),
    CodePage          = CodePage.Utf8,

using (var writer = new ArchiveWriter(Format.Zip, options))
    var progress = new Progress<Report>(e => DoSomething(e));
    writer.Save(@"path\to\", progress);

You create an ArchiveWriter object with an archiving format (e.g. Zip, SevenZip, ...), add files and/or directories you want to archive, set some additional options, and finally call the Save method. When you create Tar based archives, you can use a TarOption object for selecting a compression method.

var options = new CompressionOption
    CompressionLevel  = CompressionLevel.Ultra,
    CompressionMethod = CompressionMethod.BZip2, // GZip, BZip2, XZ or Copy

using (var writer = new ArchiveWriter(Format.Tar, options))

Examples for extracting archives

If you want to extract all files from the archive, you create an ArchiveReader object and call the Extract method. The 2nd argument of the constructor, that means the password of the archive, can be set string or Cube.Query<string> object. The latter is mainly used for implementing the interactive mode.

// Set password directly or using Query<string>
var password = new Cube.Query<string>(e =>
    e.Result = "password";
    e.Cancel = false;

// Supports only the Filter property
var files   = new[] { ".DS_Store", "Thumbs.db", "__MACOSX", "desktop.ini" };
var options = new ArchiveOption { Filter = Filter.From(files) };

using (var reader = new ArchiveReader(@"path\to\archive", password, options))
    var progress = new Progress<Report>(e => DoSomething(e));
    reader.Save(@"path\to\directory", progress);

Note that ArchiveWriter and ArchiveReader classes need to execute in the same thread from constructing to destroying. Use Task.Run() in the whole transaction if you need to archive or extract files asynchronously.
