Version 3.1
  • Support for industry-standard AES (Advanced Encryption Standard) has been added, letting you use the strongest security available on the market with your Zip files. Compatible with WinZip 9 and 10.
Version 3.0
  • Support for reading and writing Tar archives and GZipped files has been added, ensuring maximum compatibility between your applications and the data they need to work with.
Version 2.3
  • The ability to read and write in the Zip64 zip file format has been added. Gone is the 4 GB limit for files and archives, and archives can hold an almost unlimited number of files.
Version 2.2
  • Version 2.2 supports extra headers, meaning that supplementary information (in both PKWARE and Info-Zip formats) can be included in zipped files. End-users can therefore use detailed time-stamp information (last modified, last accessed, and creation date and time) and Unicode filenames (international characters).
Version 2.1
  • Increased performance. The result is that when compressing a large number of files, speed improvements in the range of 40% to 80% have been obtained. When decompressing files, the improvement is between 20% and 30%.
Version 2.0
  • Splitting and spanning: Supports reading, writing and even updating zip files that are split into multiple parts (with different filenames, like .Z01, .Z02, etc.) or that span multiple disks (with the same filename on each disk). In addition, split zip files can be located in the same folder or in altogether separate locations.
  • Full self-extracting support: Sharp, fully customized self-extracting zip files can be created. In fact, it supports all the features offered by our extremely feature-rich Xceed Self-Extractor Module, but without the added cost of an extra module to purchase.
  • With Self-extracting, you can dynamically create self-extracting zip files with install-program-strength capabilities like displaying an intro message or license agreement, showing a progress dialog, asking for passwords, running another application, creating program groups, opening documents, etc.
  • Deflate64: The Deflate64TM algorithm is now supported.
  • Updated filesystem object model: With its new memory and .NET isolated storage file and folder objects, all zip, unzip, copy, move, rename and other operations can now be performed to and from memory and .NET isolated storage, not only to disk and zip files and folders.
  • This also means that you can not only zip from memory, but you can also create a zip file entirely in memory then access, modify or copy it or its contents as if it was a real file. Also, in addition to being able to unzip from a file to memory, you unzip from a zip file that is in memory or in a stream.
