Xceed Real-Time Zip for .NET

What's New in Xceed Real-Time Zip for .NET 5.1?

• Zip format compatibility improvements and bug fixes. Specifically, compatibility with older zip tools has been increased by making it the default behavior to produce Zip 2.0-compatible archives; this behavior can be changed by the developer. Also, the ZipWriter can generate uncompressed zip files that the ZipReader can read with increased flexibility (combines the Deflate format and no compression).

What's New in Xceed Real-Time Zip for .NET 5.0?

• Compatible with .NET framework 4.0 / Visual Studio 2010

What's New in Xceed Real-Time Zip for .NET 4.1?

• WinZip 12 compatibility, supporting the LZMA algorithm for improved compression (Zip files using WinZip 12's special JPEG recompression feature are not supported)
• UTF-8 character encoding in headers for improved support of international characters in filenames and comments is provided

Xceed Real-Time Zip for .NET Major features

• Lets applications read and write fully standard Zip archives without resorting to any intermediate disk/memory storage or temporary files whatsoever. This means optimized performance ideal for high-demand server environments, Biztalk servers, diskless operations, I/O-intensive Web sites, or any situation where real-time streaming zip/unzip capabilities are needed, or where memory or disk space is at a premium.
• WinZip 12 compatible: WinZip 12 compatibility, supporting the LZMA algorithm for improved compression (Zip files using WinZip 12's special JPEG recompression feature are not supported)
• The product's main ZipWriter and ZipReader classes use any seekable or non-seekable Stream-based object as the target or source Zip archive, respectively, for complete flexibility and “on-the-fly” compression/decompression.
• Lightweight libraries.
• Creation of Zip archives begins as soon as data to compress has been received: no waiting for all of the files, or even for complete files. Doesn’t need to know in advance the number or size of files.
• Zip archives can be immediately sent over a network or saved locally as soon as the write process has begun, and the remainder of the archive becomes available as it is compressed.
• Fast: Not needing to use temporary files when creating a Zip file means it's slightly faster than Xceed Zip for .NET when it comes to creating entirely new Zip files.
• Secure: Because no temporary files are used while writing a Zip file, there is less chance of unauthorized access or modification of files during the Zip creation process.
• Archived files are extracted and available instantly for further processing even if the component is still receiving the Zip archive.
• The size or number of files in a Zip archive has absolutely no impact on memory and disk-space requirements.
• Just a few methods and properties are needed to perform powerful Zip compression/extraction.
• Supports the BZip2, BWT, Deflate, Deflate64™, and PPMd compression methods. (The PPMd compression method is only available in 32-bit applications.)
• AES encryption and decryption are supported for maximum WinZip compatibility.
• Events and properties to monitor and control the Zip writing/reading processes are also provided.
