Could someone remind me what is XML file used for?
The name is .xml. It seems to be autogenerated under some conditions.

Ah, it’s generated when I press “Generate” button in the BOM window (even with no plugins present).
Actually it’s so called Intermediate Netlist that exposes logical properties of schematic for easy processing.

Please start a new topic instead of appending to a 10 year old topic. I think XML can still be generated with the legacy BOM export but I am not sure nor do I need it.
