Key notes
A Windows Cabinet (CAB) file, earlier known as Diamond files, is a single file that stores various compressed files in a file library and usually comes with a .cab extension.
The file is similar to ZIP files as they both use DEFLATE, Quantum, and LZX compression algorithms to compress the files in them. If you want to open and install a .cab file on Windows 11, this guide can help!
What should you do before starting the .cab installation?
After making these checks, you can continue with the installation process.
How can I install .cab files on Windows 11?
You can use the same command to install the .cab file on an earlier version of Windows andto extract a .cab fileon Windows 10/11.
