The .CAT file type is a Microsoft Security Catalog file, which stores information about the digital signatures used to verify the integrity of a software application or driver. This file type is primarily associated with the Microsoft Windows operating system. It is essential for the security and integrity of devices and software. Each entry in the file contains information about the code signed using Authenticode, including the hash algorithm, cryptographic signature, whether or not revocation information has been requested, the timestamp, and more.
The CAT file contains information that helps ensure that a given piece of software or driver is authentic. It is used for system files such as device drivers and programs as well as other digitally signed files such as executables, ActiveX controls, script files, and cabinet files. The CAT file can be used in applications such as Driver Verifier, Code signing, and Software Restriction Policies.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .CAT) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .CAT extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .CAT file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .CAT extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .CAT extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .CAT file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .CAT file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .CAT file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .CAT file) will be extended to the maximum.
It is also good to check
- if the .CAT file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
