Splitting and spanning

　　Xceed Zip for .NET adds support for 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

　　Xceed Zip for .NET can now create sharp, fully customized self-extracting zip files. 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 this, 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.
