How to Extract CAB Files in Windows

The need to transfer files is ever increasing. It has, however, been faced by the challenge that some files, especially the ones containing software, are extremely large and would take ages to transfer normally. This challenge has led to the wide usage of archive file formats such as CAB. In this article, we’ll look at how to use CAB files in Windows Operating System.

You might have downloaded or received a file with the extension .cab. Given how rare this format is, many people are afraid to extract such files suspecting that they might be malicious. This is not the case.

CAB files (short for Windows cabinet files) are lossless data compression archive files. This means that they store multiple files and folders and package it into one file, reducing their size in disk space. They are commonly identifiable with their filename extension .cab.

They employ compression algorithms such as DEFLATE, Quantum and LZX. CAB files are used in windows files such as system files and drivers. Common examples of software that use these files are installation engines like device installer, Setup API and advpack.
