How to Open a DAT File
A DAT file is used for a variety of reasons. Files with a DAT extension are generally composed of information stored by programs. Such information includes configuration information or simple data. Some programs will write codes that seem jumbled/messy into DAT files. Regardless of the application, DAT files can be opened and read by a variety of different tools.
The most common tool is a text editor. Text editors can easily open nearly any type of file. Notepad is a common text editor that is available on most PC systems. In order to use Notepad to locate the DAT file, select the “File” tab and choose the “Open” option. This will open a browser window that allows the user to navigate to the directory that contains his/her DAT file.
Once you are in the directory that contains the DAT file, choose the drop down menu that allows you to select the file type (by default it is set to “Text Documents (*.txt)”) and set it to all files. In order to open it manually in the “file name:” field, type in the name of the file with the “.DAT” extension. Select open to access your DAT file.
The DAT file opens right away and displays its contents in the Notepad window. Large DAT files may take longer or may fail to load if it is too large for Notepad to handle. Using an alternate text editor may be necessary to open larger DAT files.
Note: Do not change anything in the DAT files as doing so may damage the programs that require them. Just to be safe, backup the original file before making any changes to it. Keep in mind that changing information in DAT files may prevent the computer from starting up in the next reboot or cause some programs to malfunction or stop functioning altogether. One must take great care when dealing with DAT files.
Remember that DAT files are used for a variety of reasons and may or may not have changeable information for the user. The way information is displayed depends on the text program being used to view the DAT file. Files with their extension renamed to DAT may still be readable with the program that created them.
