What is CAB file?

A .cab file, also known as the Windows cabinet file is a collection of multiple files stored together like the ones we arrange in a physical world. This file format is used mainly to put together several data files that are used while the Windows Installer installs a new application on the user’s computer.

The structure of the .cab also allows storing a very large and complex compressed file to be stored in chunks of several cabinet files. This file is also usually accompanied by an .inf file which stores the information in form of the metadata to use the cabinet file properly. Cabinet files have the feature of digital signature which allows the users to check its authenticity.

We hope we helped you solve the problem with the CAB file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the CAB file (apart from the lack of the proper application installed).

First - the CAB file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the CAB file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the CAB file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the CAB file has not been completed and it cannot be opened properly).
