That is a good sign.
In the SVT Tree (the list of modules), that icon (often looking like a green checkmark or a green shield with a symbol) next to a CAFD file means:
1. File Found: E-Sys has found the matching coding data file in your laptop's library (PSdZData).
2. Ready to Code: The module is readable and can be coded.
If you saw a Red icon or a missing file symbol there, it would mean your software data is too old for the car, or the file is missing. Since they are green, you are good to go!
