Description

A cabinet file stores multiple compressed files in a library. It is an efficient way to package data and is often used for creating software installation archives. Examples of installers that use cabinet files include device drivers, software updates, and network components.

Developers can use cabinet creation tools such as Makecab.exe and Cabarc.exe to create cabinet files for use with a software installer. Large files can be spanned across multiple cabinets, but each cabinet can have a maximum of 15 files that span to a second cabinet file. The installation utility, such as Windows Installer, extracts the files in the same order they are stored in the cabinet file.

Important: CAB files may be located inside or outside of an .MSI file.
