What is an .CAB file?

.CAB is Windows Cabinet File

A CAB file is a Windows Cabinet file saved in an archive format native to Microsoft Windows that supports .ZIP, Quantum, and LZX data compression algorithms. CAB files contain compressed data and is used for Windows software installations such as system files, network components, and device drivers.

The Microsoft installers Setup API, Device Installer, and AdvPack often install data from CAB files.

To run the Microsoft System Configuration Utility (msconfig.exe), a program that reads CAB files, select "Run" from the Windows Start menu, type "msconfig," and press Enter.
