Have you encountered a problem with a DAT file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a DAT file here. In the further part of this page we have added a list of programs that should open your DAT file. It is enough you choose a proper application for your operating system, download and install it.


The extension DAT is generally used for datafiles, ie data files. DAT files are nonspecific and can not be assigned to any data type. They can contain anything, graphics, audio, texts or simply data of the generating program.

Dat files are used and generated by quite a few programs and can normally only be used by these programs. You can use a text editor or rather a hex editor to easily view (look in) the file. However, these data views are usually useful only if there is a lot of prior knowledge on the part of the user.

Data files are for example used by Microsoft Visual Studio, Winamp, Windows and Firefox as well as many games.

How to open a DAT file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the DAT file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a DAT file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support DAT files. At this point we are looking for disk space where the application was installed in and we can link it with a DAT file. Since then, our operating system will use the selected program to support all DAT files.

Other issues

Despite the described problem with DAT there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the DAT file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the DAT file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
