•the ecom files should be numbered in a row.... for example: ecom-2-0.spi is always ...-0.spi, then first language would be for example: ecom-2-1.s01, then for example: ecom-2-2.s03 --> now you can't have two with the same second number, so the next one is not allowed to have -1 and -2, but they can have any other number
