什么是CAB文件？
A CAB (Cabinet) file is a compression format used by Microsoft Windows for software installation packages, system updates, and driver distribution.
CAB files use MSZIP, Quantum, or LZX compression. They are commonly found in Windows Updates (.msu files), driver packages, and application installers.
7-Zip can extract files from CAB archives, allowing you to access individual files without running the installer. This is useful for extracting specific drivers or system components.
