Opening CAB files

Did your computer fail to open a CAB file? We explain what CAB files are and recommend software that we know can open or convert your CAB files.

What is a CAB file?

Files that contain the .cab file extension are archive files. The "CAB" in the file extension stands for the word "cabinet", which is in reference to the nature of these files.

A CAB files takes multiple files and stores them in a single archive folder. The CAB file format allows for the compression of the files so that the file size of the "cabinet" is much smaller than it would be if each file were stored or transmitted individually. This makes it much easier to transmit large batches of files over the Internet or via email.

Many Microsoft applications use the CAB file format for their installation engines, such as the Setup API, Device Installer and Windows Installer applications.
