Slot holes file question


I’m going to order several designs for your PCB service and I have a question. I made the question on other topic but I received no answer.

I need some slot holes for a component. From the design software (Altium) I get 2 holes files: RoundHoles.TXT and SlotHoles.TXT. How do I send them? As separe files?
On previous orders I only used round holes and obviously I had only one holes file.

Thank you very much.

Send them us, and we will send them to the fab to see if they are ok.
