For this tutorial I will explain how to batch files with umodel in cmd. This can be used if you are having issues with crashing or other errors that prevent you of dumping the full folder. 

You can see there are several settings you need to change in the file for it to find everything correctly.  Everything is pretty much laid out for you just change the locations of the file paths. 

In this script we are using "Destruction Allstars" as an override.  These are called the taglist. You can do this by using cmd drop in umodel.exe [space] -taglist.  Once you have the abbrevation of the game you can enter that into the set game=. 

Set the version of umodel in set umodel=

Here is a list of all functions, it will help you to understand the functions of the script.
