Xceed Zip for .NET Compact Framework is a data compression and all-purpose file manipulation class library for creating mobile apps. It provides flexible zip, gzip and streaming data compression capabilities for compact applications created with Visual Studio .NET 2003. The library includes an innovative and extensible filesystem object model that makes zip files as easy to work with as regular files or folders.

.NET technology

• 100% managed code written in C# (Complete source code included in the Blueprint Edition)
• Entirely rewritten and redesigned - not a .NET interface over a recycled ActiveX component like some other manufacturers are trying to sell :-)
• Object-oriented design created specifically for the .NET framework
• Seamless integration with the .NET base class libraries
• All error handling works through .NET exception classes
• Objects don't need to be explicitly disposed of
• CLS compliant (Common Language Specification)
• Does not use unsafe blocks for minimal permission requirements
• Documentation fully integrated into Visual Studio.NET

Major features

• Create new zip files or update existing zip files on disk or in memory
• Zip or unzip to and from disks or memory
• Read, write and update zip files split into multiple parts
• Read, write and update zip files that span multiple disks
• Create powerful fully customized self-extracting zip files
• Supports the Deflate and the new Deflate64 compression methods
• Supports the GZip, Zlib, Info-Zip, Java and proprietary compression formats that include embedded checksums to ensure data integrity
• Can read/write ".gz" GZip files used on Unix / Linux platforms and provides access to GZip header information fields
• List contents of a zip file with complete file specifications
• True .NET pass-through stream object that can automatically compress or decompress any other type of .NET stream's data
• Compress and decompress byte arrays
• Calculate CRC-32 and Adler-32 checksums on streams or byte arrays
• Copy, move, rename, delete and change attributes of files and folders in a zip file, on disk or in memory
• Zip password encryption
• One-line shortcut classes for basic zip file and compression operations
• Fully extensible classes so you can customize the library's functionality as needed
• Information-rich status report events with percentages, byte and file counts
• Programmable filter system to limit processing to specific files or folders, with built-in filters for file attribute, size, date timestamp and filenames. Create your own custom filters as needed.

Other features

• Zip password encryption on a per-file basis
• Recursively zip or unzip entire directories and their contents
• Control the path information stored in the zip file for each file or folder
• Zip or unzip only files newer than those already in the zip file or destination folder
• Overwrite files only in certain conditions
• Split zip file can use the Pkware or Xceed naming convention for each zip file part or create your own custom naming convention
• Split zip file parts can be written to different folders
• Triggers only the events your application subscribes to for increased performance
• Get and set individual file comments or the global zip file comment
• Supports different encryption passwords for each file
• Controllable compression levels and methods
• Zip files currently open for write operations by other processes
• Supports long filenames and UNC paths
• Ability to preview which files will end up being processed
• Process system and hidden files, overwrite read-only files
• Self-extracting Zip file features
• Create new self-extracting zip files or transform already existing zip files into self-extracting zip files.

Self-extracting zip files can span multiple disks

• Creates 32-bit self-extracting zip files that work on all Windows 95, 98, ME, NT, 2000, XP operating systems or 16-bit self-extracting zip files that work on Windows 3.x as well
• Update and reconfigure an existing self-extracting zip file
• Customizable introduction message and dialog box titles
• Display a license agreement with configurable accept and refuse buttons
• Customize all other messages, prompts and button captions
• Set the default unzipping folder
• Allow user to select an alternate unzipping folder
• Request a password whenever an encrypted file is encountered
• The user can enter the decryption password or skip the file if they don't have the password for the file
• Display a text file after successfully unzipping files
• Customizable overwrite behavior with dialog box offering the user various overwrite options
• Display unzipping status
• User interaction and dialogs can be selectively shut off for quiet operation
• Execute one or more applications (optionally with parameters) or open documents after successfully unzipping files
• Copy one or more files from one location to another after unzipping
• Register DLLs (or other libraries) on the system after unzipping
• Add or change key values in the registry after unzipping
• Create self-extracting zip files with a built-in decryption password. This prevents users from using unzipping programs to unzip the files, and therefore forces users to view your custom introduction, license agreement or warning messages
• Create program groups and insert items into program groups
• Associate filename extensions with applications
• Allows 3rd-party install or setup programs (and their data files) to be unzipped into a temporary folder, executed, and then deleted upon completion
• Custom paths, filenames, strings and prompts are parsed, allowing you to insert strings such as the current folder, windows and windows system directories, the temporary folder, and more
