Or manually extracted.

Why or what do you need the BLP for?

KISWB (ie chassis information).

But what is the difference if the BLP files are present or not, what is different?
Do you need the BLP files to work with Ista, whether with ICOM or other interface?

Interface does not matter to BLP. You need files for 'Basic features' and vehicle identification.

Ok but I do not have the BLP files, and never had any problems with basic functions or identification ..

I use the BLP with Launcher console or manually in C: Rheingold / PSdZ / data?
Do I have to see what happens then.
