About:
Gcab is a command-line tool and library for creating and extracting Windows Cabinet (.cab) files. It serves as a key component of msitools, an open-source alternative to WiX for building MSI installers. The tool provides a robust solution for handling the cabinet archive format commonly used in Windows software distribution.
Key Features:
  • Create and extract .cab archives via CLI
  • Library for programmatic cabinet manipulation
  • Part of the msitools suite for MSI creation
  • Open-source implementation of CAB format
Use Cases:
  • Building Windows installer packages on non-Windows systems
  • Automating cabinet archive creation in CI/CD pipelines
  • Extracting files from existing .cab archives for analysis
Alternatives:
  • cabextract – cabextract is extraction-only, while gcab supports both creation and extraction
  • WiX Toolset – WiX is Windows-only and proprietary, while msitools/gcab is cross-platform and open-source
