Yes for me that is fine, but my wish is to provide a script that is
useful for more users (the script is part of a bigger project I work
on). If needs to be I will warn user to make a smaller file, but
ideally I think it is still feasible to somehow come up with an
efficient (e.g. 1 second even for big big file) way.

Kind regards,
