Some of you may have gotten stuck with the .DAT file at some point which should have been an MS Word file. And now you don’t know what to do with it.

Here, in this tutorial, we will introduce you to the world of DAT files, what they are, why they are used, how to open them, etc.

What is a .DAT File?

The .DAT extension is a generic file that contains critical information about the programs used to create a specific file. It could be in text or binary format. However, in some rare cases, you can find them in the form of actual video file data for VCDGear, CyberLink PowerDirector, and other similar programs.

They can get into the email attachment file as winmail.dat file, video, image, document, etc. which are typically created by Microsoft Exchange Server. But many other programs create DAT files and references to a specific function in their respective programs.

Usually, these files are hidden in the application’s data folders, but you may still see them often if you’ve received an ironic attachment in your email with the extension or if you’ve similarly archived a video file.

Often the name tells us what type of file it is, otherwise it is really difficult to understand what type of file you are dealing with, be it text, images, movies or something completely different.

For instance:

The name of the DAT file indicates that it is an audio file

Here, the file name indicates that it is an audio file.

How To Open The .Dat File

These files are generally designed to be used by applications and not to be opened manually. This file in games like Minecraft stores blocks of levels which are loaded as the game progresses. You can open them with programs that have been created for that purpose or you can even use a text editor or VLC. Opening a DAT file depends on the type of file you are dealing with and the information it contains.

Using the text editor

You can use any text editor to open a DAT file. All text editors have a different process for opening a DAT file but are easy to use.

Right click on the file you want to open and select the “open with” option. And then choose your text editor.

Now, if the file is text based, it would look like the image below:

If not, it will look similar to the image provided below:

If your text editor looks like the image above, it means it’s not a text file and you need to open it with other tools or not open it at all.

Opening video DAT files

As mentioned above, some programs like VCDGear or CyberLink PowerDirector have video DAT files. You can open these files with the programs that contain them in their folder or you can use VLC.

Right click on the file you want to open and select the “Open with” option. Then select VLC from the menu. But don’t hope high as most of the .DAT files in your program directories would be pretty useless as they are often gibberish computer code, well, most if not all of them are.

Converting DAT files

If nothing works and you have no idea of ​​the source of the .DAT file, converting them to other formats like text, audio, or video might work. Sometimes, VCD files that use the .mpg format may end up being stored as DAT files.

If so, all you need to do is right-click on the file and go to properties. In place of the file name, replace .dat with the format in which you think the original file is. However, before starting the process, make a copy of the file and then convert it as the wrong conversion could damage the file.

Many other programs also use DAT files. Bitcoin Core uses the Bitcoin client wallet file called wallet.dat. The Porteus Linux operating system saves its container files with the DAT file extension. For Piriform applications, they store portability and registration information. While the Windows registry stores hives and other registry information in DAT files.

The uninstallation information for Inno Setup is stored there. These are just a few examples of DAT files that don’t need to be opened manually. If you do, they will become corrupt and useless.
