  • The richest feature set with over 200 capabilities
  • Supports the latest zip file format standards
  • Used and trusted by Microsoft in their server products
  • Supports .NET 4.5, 5, 6 and 7 (including .NET core and .NET Standard)
The only Zip library compatible with all the latest updates to the Zip archive format, including UTF-8 to support all characters in filenames, and LZMA for WinZip 12+ compatibility.

Trusted

The most advanced and reliable .NET compression library on the market. Used by Microsoft, Apple, Adobe, IBM and many Fortune 500 companies in their applications.

Solid as a rock, and updated often. Xceed’s 20 years of experience with data compression products for software developers gives Xceed Zip for .NET an unmatched pedigree. It is the most stable data manipulation library for .NET, so you can create robust applications that execute error-free with any kind of input data. Microsoft trusts it enough to use it in various products, including server operating systems.

Multi-Talented

Offers an industry-defining feature set. Supports the latest zip file standards, including WinZip 12 and up. No other zip library is as up-to-date. Provides every feature you will need to accomplish your goals efficiently. If you have advanced needs, it also supports recent technologies like AES encryption, LZMA, PPMd and BZip 2 compression methods, and provides Gzip and Tar support, too.

File management integration

It also provides built-in file transfer (FTP and secure FTP), file and folder synchronization, and filesystem capabilities, through an integrated interface that is simple yet powerful.

Perform complex operations with only a few lines of code. Need to update the contents of a zip file located on a remote FTP server? Stream directly to or from a file inside a zip file? Synchronize the contents of any number of folders and files? This library lets you easily do it with small amounts of elegant code. For “on-the-fly” Zip read/write in scenarios where intermediate disk/memory storage is a major concern or simply not possible, check out Xceed Real-Time Zip for .NET.

  • Supports VB.NET, C#, and Managed C++.
  • 100% managed code, written in C#.
  • Source code incouded with the Blueprint subscription.

  • NET and C# Samples include a WinZip™-like zip application, a PKZIP(™)-like console zip application, a streaming compression sample and a Windows Explorer-like application that allows you to work with files, folders, and zip files interchangeably.
  • The .NET 4.X build is compiled using .NET’s Client Profile.
  • The only library to provide WinZip 12 compatibility, supporting the LZMA algorithm for improved compression in certain situations. Note: Zip files using WinZip 12’s special JPEG recompression feature are not supported.

When unzipping one or more files from a Zip file located on an FTP site, Xceed Zip for .NET will download only the necessary portions of the Zip file required in order to unzip the files, for greatly improved speed and minimal bandwidth use.
  • Read, write, and update zip files split into multiple parts.
  • Read, write, and update zip files that span multiple disks.
  • Supports the Deflate64™ compression method, for improved compression.
  • Supports the BZip2 and BWT compression methods for improved compression when speed is less crucial.

  • One-line shortcut classes for basic zip file and compression operations.
  • Fully extensible classes so you can customize the library’s functionality as needed.
  • Information-rich status report events with percentages, byte and file counts.
  • Programmable filter system to limit processing to specific files or folders, with built-in filters for file attribute, size, date, timestamp and filenames. Create your own custom filters as needed.
  • HTTP proxy server and both FileSystem-based and FtpClient-based SSL support.
  • Efficiently creates zip files by allowing developers to decide whether folder entries should be written to the archive, which reduces its size.

  • Need “on-the-fly” Zip file read/write capabilities for use with high-demand servers or Web sites, etc., where intermediate disk/memory storage is a major concern or simply not possible? Check out Xceed Real-Time Zip for .NET!
  • Built-in file transfer and filesystem capabilities. Because it’s built on top of the Xceed Filesystem Core, a variety of additional file and folder manipulation capabilities are available, as is the complete functionality of Xceed FTP for .NET without any additional learning curve or effort.
  • Abstracts the concept of files and folders in Zip files, on FTP sites, in streams, in memory, etc., so that your code is written as if it is working with regular files or folders. When support is added for more archive types and locations, there is no need to change your code in order to work with the new archive types or locations.
  • Optimizes operations so that you can perform feats such as speedily accessing files located in a Zip archive on a remote FTP server, while using astonishingly low bandwidth. No other .NET component or combination of components can accomplish this.
