Saving Reports
For most of this course we'll be using the .pbip (text-based) file format because it's easier for the bootdev CLI to check. However, the .pbix (Power BI Report File) binary file format is the standard for Power BI reports, and generally speaking is the better choice for data analysts working in GUI (graphical user interface) environments.
.pbip is a newer file format, introduced in 2023. It's mainly used by developers who want to store Power BI reports as text files so they're easy to track in version control (like Git).
It's important to note that the data files themselves (in our case the .csv files) are not stored in the .pbip file. The .pbip file contains metadata about the data sources, transformations, and visualizations, but for your report to work, you also need the original data files.
It's a very good idea to save your work regularly, especially before making big changes. Power BI does not auto-save, so getting into the habit of saving often will help you avoid losing progress.
