What's this all about?

7-Zip-NBinding is a .NET wrapper for 7-Zip C++ library. It allows extraction of many archive formats using a very fast native library. The implementation is based on 7-Zip-JBinding (generated by IKVM). Featues:

  • Extraction of
    7-Zip Zip Rar Tar Split Lzma Iso HFS GZip
    Cpio BZip2 Z Arj Chm Lhz Cab Nsis
    Deb Rpm Udf
  • It's cross-platform (using Mono on non-Microsoft operating systems). Native binaries included for:
    › MS-Windows 32/64 › Linux 32/64 › Darwin Mac OS X
  • Full support for password protected and volumed archives
  • Planned: Creation of 7-Zip/Zip archives
  • Planned: Extraction of more archive formats: Compound, Dmg, Elf, Hfs, Macho, Mub, Pa, Split, Wim

How does it work?

The 7-Zip-NBinding consists of three parts: the .NET part, the java part and the native part. The .NET part makes it easy to access java part. The java part introduces a cross-platform java interface of the 7-Zip library. The native part of 7-Zip-JBinding communicates with the java part through the java jni interface and uses the corresponding native 7-Zip interface to perform operations.


It's really simple!
