Open .DAT File Extension In Windows Quickly
Do you have a .DAT file in your computer and don’t know how to open it? Firstly .DAT file could be anything like a picture, video, data, email attachment, etc. To open .DAT file you will have to find out what kind of file it is, you can than convert the extension to open it easily. If you don’t know what kind of file it is, you can determine it too. More details after the jump.
.DAT file is never associated with any one program. You can try opening it with notepad and MS Document. If it is a chat session or some text document then it will display the content, otherwise it will show some rough data that only programmers can understand.
Your .DAT file could be anything like a video file or a document, the best way to determine would be to add different extension in place of .DAT extension and see if it works. To do this, follow the method below.
Go to Tools > Folder Options and click View tab. Now uncheck the Hide Extensions For Known File Types checkbox and click OK.
Now you will see file extension at the end of every file on your computer. Now change the extension of your .DAT file to .JPG, .PNG, .DOC, .XLS, .AVI, one by one and check if it works. Opening it with IrfanView might solve the problem, as it opens most Picture and Video extensions.
If this method doesn’t work, then it means either you have a Email Attachment, or a Video file.
Winmail.Dat Email Attachment
If you have a file named Winmail.dat, this means you have received this file as an attachment in the email and the sender has used Microsoft Outlook, Outlook Express or MS Exchange Server to send you this mail.
To easiest way to open it is to use an online converter called WinMailDat.
VCD Video File
If you find a video file in .DAT extension. You can easily open it using VLC Media Player. But if you want to convert it so that it can be easily played on other video players than you can use VCD Gear to convert .DAT extension to .MPG easily.
That’s all. If it solves your problem, don’t forget to say thanks. If you are still in trouble, feel free to leave a comment.
Please, how do i open a .dat file with geographical locations. Maybe using GrADS which will open a data file with .dat file into different geographical location that will give the data like temperature, wind speed or relative humidity.

A .dat file is often a file from a popular application that got its extension changed by Outlook, the computer or the copier that saved the file.
When receiving a .dat file, try to think what kind of file it could be: a Word doc, an Excel file, a Powerpoint file, an Adobe .pdf or a scanned jpg?
According to your estimation, try to change the extension to the expected extension and see if you can open it.
In most case, when I try to open a .dat file I try to open it with Adobe Acrobat or Irfanview and that works in 70% of the cases.
Once opened with the right software you can save the file with the right format.
Hope this helps, good luck!
Didn’t help. I gave up after trying numerous ways.
Sir,
I was having a problem to play my video files with .dat extension name. With your kind guidance I changed its extension name to .AVI and now these are playing very nicely.
I am grateful to you for your valuable guidance. The problem resulted from Re-Formating of my PC by some body who downloaded software/programs which were not in consonant with the data already available on my disc. A lot of thanx please.
Thanks a lot for the information.It’s working…..!

just drag the file to notepad window/icon and check to see if notepad window shows some comprehensible content. if it doesn’t then it probably doesn’t have any text data in it that could be worth of you. if you expect any type of multimedia in it then just open it by dragging *.dat file to vlc media player as it is able to play any media container file irrespective of it’s extension.
