What is it?
CAB, short for Cabinet, is an archive file format developed by Microsoft for the Windows platform. It supports lossless data compression and can store embedded digital certificates to verify the integrity of the archived contents.
A cabinet file is identified by the magic bytes 'MSCF' at the start of the file and groups multiple files into folders that are compressed as a unit. It can use either the MSZIP (DEFLATE-based) or the more efficient LZX compression algorithm, and large installations can span multiple cabinet volumes.
Technical Specifications
Pros & Cons
Advantages
Supports the LZX algorithm, which achieves higher compression ratios than the DEFLATE-based MSZIP method.
Cabinets can carry embedded digital certificates, allowing Windows to verify authenticity before installation.
A single logical archive can be split across several .cab files to suit removable media or download chunks.
CAB is handled directly by Windows Setup, Windows Update, and built-in tools such as expand and extract.
Disadvantages
Tooling and ecosystem support are concentrated on Windows, with limited native handling on other platforms.
CAB has largely been superseded by MSI, APPX/MSIX, and modern installer formats for application distribution.
It is rarely chosen for everyday file compression compared with ZIP or 7z.
When to Use It
CAB is used primarily within the Windows software distribution and installation pipeline.
Softwareinstallation
Setup packages and MSI installers store compressed payloads inside cabinet files.
Gerätetreiber
Windows driver packages and Windows Update deliver components as signed CAB archives.
Systemupdates
Windows servicing uses CAB files to package and deploy operating system updates.
How to open a CAB file
CAB files, or Windows Cabinet Archive files, are commonly used for compressing and packaging multiple files into a single archive. Software for handling CAB files falls into several categories: professional tools for enterprise use, free and open-source options for casual users, browser-based tools for quick access, and built-in utilities in operating systems. Each category serves different user needs, from comprehensive features in professional software to simplicity in built-in tools.
When choosing software for CAB files, key factors include feature fidelity, the ability to edit versus just view, cost, and platform compatibility. Some users may prioritize free options, while others might require advanced features available in paid software. Additionally, understanding when to convert CAB files to other formats can influence the choice of software, especially if interoperability with other systems is necessary.
