I looked at a programming interface like the function “opendir”.
I imagine that there are more advanced possibilities to improve the software
run time characteristics for this use case.

I hope so.

Thanks for your interest.

Something like that.

I would like to avoid such an operation “Remove matching prefix pattern” 
generally.
If the desired file lists contain only basenames, extra prefixes do not need
to be deleted.
