Can't create a .bat file with ROMLISTER

[OlDirty]

Hi

I followed this tutorial of ROMLISTER 031.2 ( https://www.gameex.com/Portals/0/Romlister%20Tutorial.pdf )and wanted to create a bat file for my horizontal and vertical MAME games.
I come to the step where you can "Save List to file". In the file type drop down menu the Save as type "batch files" should be available, but i can just save the list as a .txt file. Any advice? It's the first time i'm using ROMLISTER. I use Win10. Thanks in advance.

EDIT: Problem solved. I have choosen "ROM Names only" as described in the PDF, but i should have choosen "Batch file".
