Rebex.Zip 8.0.9797

Rebex ZIP - The C# ZIP compression library for .NET

Rebex ZIP is a ZIP, UnZIP, DEFLATE, zlib and GZIP compression library for .NET. It makes it easy to create, modify, encrypt, or extract ZIP archives. Compatible with WinZip, PKZIP, Info-ZIP, and other tools.

15+ years of active development. Rebex ZIP has been continuously developed and maintained since 2010, with regular updates and new features.

Key features

• Single file operations - add, extract, delete, rename, move files; compress from and extract to memory streams
• Multiple files operations - batch add/extract with wildcards, recursive directory transfers
• Directory operations - create, rename, delete directories within archives
• Password protection - WinZip-compatible AES-128/192/256 encryption and legacy ZIP 2.0 encryption
• GZIP - compress and decompress GZIP archives, stream-based API
• Advanced ZIP features - multi-core compression, ZIP64 large file support (4+ GB), integrity checking, compression streams (DEFLATE, zlib, GZIP)
• Async/await API - Task-based asynchronous API support
• FIPS 140-3 compliant mode

Getting started

Create a ZIP archive

using (var zip = new ZipArchive(@"C:\MyData\archive.zip", ArchiveOpenMode.Create))
{
    // add a file
    zip.AddFile(@"C:\MyData\file1.txt");

    // add all files from a directory
    zip.Add(@"C:\MyData\Web\*");
}

Extract a ZIP archive

using (var zip = new ZipArchive(@"C:\MyData\archive.zip"))
{
    // extract a single file
    zip.ExtractFile("file1.txt", @"C:\MyData\Out\extracted.txt");

    // extract all files
    zip.ExtractAll(@"C:\MyData\Out", ActionOnExistingFiles.OverwriteAll);
}

Add and extract from memory

// add a file from stream
var data = new MemoryStream(Encoding.UTF8.GetBytes("Some text"));
zip.AddFile(data, "file1.txt");

// extract a file into memory
var output = new MemoryStream();
zip.ExtractFile("file1.txt", output);

Password-protected archive

// set password and encryption algorithm
zip.Password = "SecretPassword";
zip.EncryptionAlgorithm = EncryptionAlgorithm.Aes256;

// add files (they will be encrypted)
zip.Add(@"C:\MyData\private\*.*");

One-line static methods

// add a file to a ZIP archive (creates the archive if needed)
ZipArchive.Add(@"C:\MyData\archive.zip", @"C:\MyData\file1.txt", "/");

// extract all files from a ZIP archive
ZipArchive.ExtractAll(@"C:\MyData\archive.zip", @"C:\MyData\Out");

// encrypt an existing archive
ZipArchive.Encrypt(
    @"C:\MyData\archive.zip",
    @"C:\MyData\encrypted.zip",
    "SecretPassword",
    EncryptionAlgorithm.Aes256);

Multi-core compression

// specify preferred number of compressor threads
zip.Options.CompressorCount = 4;

GZIP compression

var gzip = new Rebex.IO.Compression.Gzip();

// compress a file
gzip.Compress(@"C:\MyData\file.txt", TraversalMode.MatchFilesShallow, @"C:\MyData\file.txt.gz");

// decompress a file
gzip.Decompress(@"C:\MyData\file.txt.gz", @"C:\MyData");

Check archive integrity

var result = ZipArchive.CheckIntegrity(@"C:\MyData\archive.zip");

if (result.Success)
    Console.WriteLine("OK - The file structure is valid.");
else
    Console.WriteLine("{0} - {1}", result.Status, result.ToString());
