A DAT file is a generic data file created by an application. It could be data from your accounting system, your automated PBX, Windows or any other program. DAT files sometimes contain configuration information or other data that more advanced users can modify to change a program's behavior. Use a generic text editor to edit the contents of a DAT file.
Click "Start | All Programs | Accessories | WordPad" to launch the WordPad text editor.
Click "File" and "Open." Change the selection from "WordPad Documents" to "All Documents" on the right side of the file selection dialog box.
Locate the DAT file you wish to edit and double-click the file to open it. Edit the file in the WordPad window.
Click "File" and "Save" to save the changes to the file, then choose "File" and "Exit" to close WordPad.
