Reza Rad wants to see exactly where the M scripts in a Power BI Desktop file are stored:

Talking about Power Query; DataMashup file is all you need. It includes everything from the structure of queries, tables, parameters, list, to the actual M scripts behind the scene. You can Fetch all of these information from this single file. Let’s look at the structure of this file. If you open this file with a text editor. you will see some binary things first (which are related to the zipped nature of this file), and also some XML information. Yes, this is a zipped file.
