Dear members.

could anyone here help me please ?

I am willing to pay.

thank in advanced.

In Windows, right-click DAT file you want to open and then click the “Open With” command. In the “Open With” window, choose the text editor you want to use and then click the “OK” button. Provided the file you opened is text-based, you should be able to read the contents.
