  • [The corresponding .NET 3.5 build is v4.4.]

    Update 5.3.13163.12170 released March 25, 2013. (Documentation now compatible with Visual Studio 2012.)

Also, the ZipWriter can generate uncompressed zip files that the product's ZipReader can read increasing flexibility (combines the Deflate format and no compression).

  • Introduction of Xceed Real-Time Zip for .NET. Lets applications read and write Zip archives without resorting to intermediate disk/memory storage or temporary files. Its optimized, “on-the-fly” performance is 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. Archives and extracted files are immediately ready for processing while data or the archive is still being received. Supports the BZip2, BWT, Deflate, Deflate64™, and PPMd compression/decompression methods. AES encryption and decryption are supported for maximum WinZip compatibility. Events and properties to monitor and control the Zip writing/reading process are also provided.
