nuendo incrementing audio file name... how/why ?

hello,
so no it still doesn’t work. i set this parameter to 0 and i still have a file that is created in advance as soon as i arm rec and how ever the pool is empty or trash removed doesn’t matter my number does not go back to _01 until i close open session … very annoying.
so when you want those numbers to be consistent you really have to make sure you don’t mess the recording or you have to restart session to have it clean. i mean… you can manually rename it but as i said it depends of how many files you are recording.
