This tutorial will cover how to package your mod from a 'data' folder into a Dat file. One of the main advantages of putting your mod into a dat file is that you dont have to worry about setting the *.pro files as read only and it's also a whole lot tidier.
Step 1 Edit
There are various Dat packers available, I prefer to use Dat2 with the Dat2 Frame Gui from Team X.
Step 2 Edit
Download the above files and place them into a folder on your computer.
Step 3 Edit
Run the file called 'DAT2Frame.exe' you should now have the screen below on your computer.
Step 4 Edit
In the 'Source Files Directory' browse to your mods data folder. Then in the 'Destination Dat Filename and Patch' enter the location and dat filename that you want. Now just click the 'Build Dat File' button, wait a few moments for the dat file to build and your finished. You now have your mod compressed into an easy to distribute dat file.
