What is a DAT file
DAT stands for Data files or otherwise called DAT files. Most dat are those data-based files which consist of information of the software application or computer program files that created them in the first place. Or that they are somehow associated or linked with.
The dat file is a generic data file which can be a generic text file or another type not meant to be opened. The best way to open a dat file is with the program that created it. But, usually you don’t know which program created the file.
The first thing you should know is that there are many computer programs that can actually open DAT files or .dat extensions. There are basic software applications on your personal computer, such as; your windows Notepad app for text based dat files .
This text editor software application will open those files that consist of simple text-based information. While text editors can be used to open a simple text based dat, there are also more complex that cannot be opened by simple text editors can open it.
For example, the codecs for different languages that are stored up and utilized by your personal computer cannot be opened by a standard text editor. But rather with by other more advanced computer programs or applications you can read a dat file.
If you don’t have any available dat viewer, check the list below.

If a Microsoft Exchange Server is responsible for sending you an email attachment, then there is a high possibility that the attachment you receive will appear as a .dat file extension. While only 42 programs are listed above, there are several more software applications and computer programs that are capable of referencing, creating, and also launching file extension DAT.
Note that dat are created by software applications and are exclusively designed to be used by the apps that are responsible for designing the respective DAT.
Therefore, DAT files are not meant to be manually opened by the user of the software application. Instead, the application will automatically launch the executable provided the program itself is available on the computer system that will be used to open DAT. Even Minecraft the popular PC game makes use of these files when storing up the different levels in the PC game.
How to open a DAT File
The generic steps to open a DAT are given below:
- Find the .Dat in your mobile device or computer.

However, where the content of the file with dat extension you opened does not consist of text-based content, what would be visible will be a number of ambiguous characters that will appear as gibberish. Along with these characters will be many “NUL” references. It means this dat is not readable with a simple text editor.

With these text formats you can view the file with an internet browser like internet explorer, chrome or edge.
Viewing the contents
It is hard to know the actual content of the DAT files that you intend opening. You may not know whether it consists of just plain text file or maybe it contains picture, audio file or video files.
You may also not know if the files are actually a configuration file meant for a certain application on your Personal Computer (PC). So, the way a DAT file is opened will invariably depend on the content which basically is the type or form of information that is contained in the files.
However, it is quite commonplace to get DAT files like text files with plain text-based content.
Winmail attachments dat file
How to open winmail.dat files ?
Apart from opening DAT files using text editors, there are times that you receive an email converted to a .dat file format. This attachment is common with an email server like Microsoft Outlook and winmail.dat file attachments.
If Microsoft Outlook was used in creating and sending an email message and the recipient of the email does not use Outlook, the email can be received as an attachment file in the ‘winmail.dat file’ format.
Rather than informing the sender of the Outlook message to have the email resent in a HTML format, you can make use of a ‘WinMail reader’ like ‘Winmaildat.com’ or ‘WinMailReader’ to read it.
With ‘Winmaildat.com’ attachments files for example:
- You only need to first download the .dat sent to your email.
- Then, you need to click on the command option labelled “Choose File” when you go to ‘Winmaildat.com’.
- Find and select the .dat then open the file by clicking on the “Open” command option.
- With the clicking of this command option, the data file will be uploaded.
- When you click the “Start” command option, ‘Winmaildat.com’ will have it analyzed.
- The result will then appear on a page which displays all the content.
- When any of the items displayed on the .dat analysis result page is selected, it will be downloaded to either your Windows PC or Mac OS, as the case may be.
- Once the downloaded item is on your PC or Mac, you can then access, view, and read the contents of the downloaded item.
