Adeel, Drill data are always exported as Excellon Format for it is the most used. The only thing you are changing with the deferent settings are: the data is send as metric or inch (commented in the excellon-file) and the exactness of the data (digits after the comma) Excellon is, originally, an manufacturer of drilling mashines who managed toset his data-format as a quasi standard for data exchange.
