What's New in V6.0?

• When AES encryption is used and each file in the Zip archive has a different password, the InvalidPassword event is no longer fired a second time after the correct password is given.
• Features AES strong encryption, which brings security capabilities to Xceed's Zip compression library. The encryption in this version is compatible with WinZip 9.0's AES encryption, meaning that users can open zipped files created by Xceed's library

What's New in V5.1?

Delivers speed improvements between 25% and 75% in certain contexts when dealing with a large number of files.


What's New in V5.0?

Added Zip64 and Deflate64 for compatibility with new PKZip v4.50 zip file format.

Overview

This high-performance Zip and Unzip data compression library lets your applications create and manipulate 100% PKZip compatible Zip files as well as compress/uncompress data directly in memory. It's designed to offer the ultimate in flexibility while being the easiest to use product of its kind. Includes a state-of-the-art, fully documented ActiveX COM component that provides the industry's most complete feature set and the fastest multi-threaded compression engine.

This ActiveX component supports both single-threaded (STA) and multi-threaded (MTA) apartment models and has very low memory requirements. It is perfectly suited for use in environments running multiple zip/unzip operations simultaneously, can run in the background and can be dynamically instantiated for formless use.

Xceed Zip has always been known for being superbly designed and easy to use. The latest version continues this tradition, and also offers categorized properties, built-in constants and enumerations, context-sensitive F1-help, optional parameters and built-in help strings.

With Xceed Zip, applications receive detailed information about the current compression activity, have full control over each file's information as it is being zipped and unzipped and can be consulted by the library when choices need to be made. There are twenty intelligently thought-out events that are triggered by component so your application is never in the dark and can manipulate the library in real-time.

Xceed Zip is 100% compatible with the latest PKZip 4.5 zip file format as well as the traditional 2.04g format, which is the most popular data compression format for Windows, and has wide acceptance on many other platforms as well. Files that are compressed using the latest Zip format can be extracted using any of today's popular unzipping applications.

Xceed Zip includes comprehensive online documentation that is packed with examples to help you accomplish your tasks effortlessly. Fully commented sample applications are included for many languages - with more are being added continuously. You can copy examples from the help file or samples, paste them into your project, and create a Zip files without writing a single line of code!

Xceed Zip includes complete sample applications, free expert support, and includes the multi-threaded ActiveX component, a DLL interface and an excellent 16-bit support package. It works with VB, VC++,Delphi, C++Builder, Visual FoxPro, ASP, VB Script, and most any other

32-bit Windows development environments.

FEATURES

ActiveX technology

• A single fully self-contained COM object and ActiveX control written with ATL 3.0
• Requires no external compression DLLs, MFC DLLs or runtime libraries
• Both single-threaded (STA) and multi-threaded apartment (MTA) model design
• Instantiate the component dynamically without putting it on a form
• Supports multiple instances running simultaneously
• Supports both Unicode and Ansi in one single control. The library automatically uses Unicode API calls for best performance when running on Windows NT, 2000 and XP
• ActiveX control interface has all constants, enumerations and types built-in. Code completion, property categories, help strings and context-sensitive F1-help fully supported
• Works with all 32-bit development environments that can use ActiveX controls, including VB, VC++, Delphi, C++ Builder, VFP, Office, PB, VO, Web scripting languages, ASP and DCOM projects
• Also compatible with VB.NET and C#. For developers that require 100% managed code, check out Xceed Zip for .NET, our fully object-oriented Zip, Compression and FileSystem class library

Compression & Zip file technology

• Fast, low memory usage compression engine
• 100% compatible with the existing PKZip 2.04g format
• 100% compatible with the new PKZIP 4.5 format
• Supports the Zip64 zip file format allowing the creation of Zip files of practically unlimited size (no more 4 GB limit)
• Supports the BZip2 (BWT) compression method for 15 to 20% better compression than Deflate on many popular file types, especially XML data
• BZip2 compression method is excellent for compressing XML data
• Supports the Deflate64 compression method, an industry standard improvement to regular Deflate
• Zip files can contain any number of files (no more 65535 file limit)
• Regular, spanned and self-extracting zip files created by Xceed Zip can be used by any of today's existing unzipping applications, and vice-versa
• Stores and retrieves the latest zip file format extensions, allowing Unicode filenames and NT file attributes, extra time stamps and security permissions to be stored in the zip file
• No need to repair corrupted zip files. Xceed Zip automatically tries to recover from errors and reports any inconsistencies found in the zip file while unzipping

Major operations

• Zip files or memory buffers into new or existing zip files
• Unzip files to disk or directly to memory
• Compress and decompress strings or buffers completely in memory
• All compression and decompression modes support streaming and encryption
• Create fully customized self-extracting zip files with the optional Self-Extractor Module
• Convert any type of zip file (regular, spanned, multi-part, self-extracting or spanned self-extracting) into any other type of zip file
• Reads and writes zip files that span multiple disks
• Reads and writes multi-part zip files directly to hard drive
