Reads/writes Zip archives "on-the-fly" with no intermediate disk/memory storage. Lets applications read or write fully standard Zip archives without resorting to intermediate disk/memory storage or temporary files. Archives and extracted files are immediately ready for processing while data is still being received. Regular Zip compression components just can't do this!
- 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.
- 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.
- AES encryption and decryption are supported for maximum WinZip compatibility. The AES encryption algorithm used by the component can now be set by the developer.
- 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.
- UTF-8 character encoding in headers for improved support of international characters in filenames and comments is provided.
- Events and properties to monitor and control the Zip writing/reading processes are also provided.
- Compatible with older zip tools.
- The ZipWriter can generate uncompressed zip files that the product's ZipReader can read, increasing flexibility (combines the Deflate format and no compression).
