Method 1: Audio and video files

If there are audio and video files, some can be opened directly with Microsoft's own media player Windows Media Player and other media playback tools.

Generally, DAT files are not associated with any program, so you have to open them manually in Windows Media Player. In Windows Media Player, press ALT to pop up the menu list:

Select the file from the pop-up menu, and then select the Open command. Or directly press Ctrl+O to pop up the open dialog box, and locate the directory where the audio and video are located:

DAT files cannot be displayed by default. We need to click on the media files (all types) on the right and Select all files (*.*) from the pop-up drop-down list, and the audio and video files can be displayed

If your DAT file is a video file and is complex and large, or your computer The decoder is not very good, so it may take some time to open, and the player will show that the media is opening for a while

If your decoder can open the DAT audio and video player, please wait for a while. It can be played normally

But if your audio and video are not decoded, WMP cannot be opened, so you need to install a decoder or open it with a player such as KMPlayer or PotPlayer.

If it is not an audio or video file, it will freeze when you open it with the player. Do not try to open such DAT files multiple times, otherwise it will cause the risk of data damage or loss.

Method 2: Text and program files

If they are program files of other software programs, most of these DAT files are data files used for installation or operation, and usually cannot be directly Open. You can try winhex to open it

The other is a plain text file, which is actually similar to a TXT file and can be opened with Notepad, WordPad, UE, winhex and other tools.

Such files are generally configuration or backup files:

There are also special types of DAT files that can be opened but can only be garbled

Some DAT files are encrypted or of a different type. Files of special nature cannot be opened by ordinary methods, and will freeze when opened with a text editor such as Notepad
