SoundTap will label each file as follows : yyyy-mm-dd-hh-mm-ss (year-month-day-hour-minute-second) This denotes the date/time the recording was started. So they will be in sequence.
Should you choose to rename the tracks, do so in a manner that will keep the sequence identity intact.
It is very helpful to create/choose a folder for saving projects as you start up SoundTap.
