Unlock the Hidden Secrets of DAT Files: Learn How to Open Them Like a Pro in Windows 10!

If you have been using Windows 10 for a while, you might have come across DAT files by now. These files are used by many applications to store data related to program configurations and settings. Most often, these files are not meant for end-users to edit or look into but sometimes, you might need to access the data inside the DAT files. In such cases, it is essential to know how to open them without causing damage to your system.

Here is a step-by-step guide on how to open DAT files on Windows 10 like a pro:

Step 1: Determine the Application that Created the DAT File Before you can open a DAT file, you need to know which application created it. You can usually tell by the extension of the file. For example, if the file name ends with “.dat,” the file might have been created by a web browser like Chrome or Firefox. Similarly, if the extension is “.datx”, the file might have been created by a Microsoft Office application like Excel or Outlook.

Step 2: Use the Corresponding Application to Open the File Once you have determined the application that created the DAT file, you can try opening it with that application. For example, if the DAT file was created by a web browser, try opening it with that browser. If the file was created by Microsoft Office, try opening it with the corresponding application.

Step 3: Use a Third-Party Tool to Open the File If the above steps do not work, you might need to use a third-party tool to open the DAT file. There are many free and paid tools available on the internet that can help you open DAT files. One such tool is the Free File Viewer, which supports more than 300 file formats, including DAT files.

Step 4: Convert the File to a Different Format If you still cannot open the DAT file using any of the above methods, you might try converting it to a different file format. There are many online and offline tools available that can help you convert DAT files to other formats like CSV or TXT. Once the file is converted, you can open it using a simple text editor like Notepad.

In conclusion, DAT files might seem like a mystery at first, but with a little bit of knowledge and the right tools, anyone can open and access the hidden secrets inside these files. By following the above steps, you can master the art of opening DAT files like a pro on Windows 10.

Dat files are one of the greatest mysteries of Windows: why are their icons blank? Why can’t you open them? What’s their purpose? Sometimes .dat files should be left as they are because they contain vital data related to a piece of software that’s best not tampered with.

But other times .dat files can actually be media files, email files, or other file types that Windows or a given software has failed to define for some reason. In these situations .dat files can actually be opened.

Here we’re going to show you how to check what’s really contained in a .dat file and how to convert it in the rare case you need to.

What is a .dat File?

By default, .dat files don’t associate with any particular program, and they shouldn’t because the data they contain is often binary and undecipherable. However, if you want to open any DAT file, then the most universal way is to use Notepad (or, preferably, a more advanced text editor like Notepad++, which displays the internal file information far more clearly).

The main indicator of what a given .DAT file does and what software it’s attached to is, naturally, to be found in its name and the name of its directory. In the below example I can see that this particular DAT file I opened a moment ago contains audio data for the game Super Meat Boy. There’s a reason for it being there and no reason to tamper with it.

Most of the time when you open a .DAT file in Notepad (or Notepad++ in our case), it will look something like the following image.

There’s really nothing you can do with data like this except potentially mess up whatever software it’s connected to by changing something. If this is what you see inside a .DAT file, then just back out for now.

In other situations you may even be blocked from opening the .DAT file in a text editor because it’s a system file and protected by Windows.

If, however, you’re suspicious of where the DAT file came from or its purpose, you can always run a scan on the file using an antivirus app. Because they’re generic and not easily opened, .DAT files are often used as a convenient hiding place for malware.

Some .DAT files actually have easily readable, clear information inside them. This one I opened in a folder for an old MMO game contains data relating to my online account for that game.

Again, don’t tamper with it unless you know what you’re doing, but the point is that sometimes there may be useful and readable stuff in a .dat file.

Convert .DAT Files to Other Formats

In some cases, if you’re sure you know the source of your DAT file (such as whether it was a video file), you can try to open .DAT in other formats, such as audio or video.

VCD files (which use the .mpg format), for example, can end up stored in the .dat format.

In a case like this you can just right-click the .dat file, click Properties, then replace the “.dat” in its name with “.mpg” or whatever format you believe the original file was in. We strongly recommend doing this on a copy of the original .dat file, rather the original, because it could break the file.

When you’re done, click OK, and the .dat file will be in a media format and will, with a bit of luck, actually work.

Conclusion

For the most part, .dat files are a byword for a vast, diverse range of software-critical files that aren’t to be tinkered and tampered with. They’re obscured for a reason and normally contain complex piles of binary data that isn’t readily modifiable.

But if you believe that a given .dat file contains some kind of playable media, which is sometimes possible, then create a copy and by all means play around with it to see if you can open it in the relevant format. But we stress again, tinker around on a copy, not the original file.
