group file name and set lable by JSL looping, work fine but slowly

BayesRabbit7133 — Thu, 22 Feb 2024 08:24:11 GMT

I have a JLS works fine, but slowly, is there any method to improve it?

1. import multiple files

2. base on file name rule group into a, b, c, d, e

3. base on file name rule to decide file count and set into rows for each group

Names Default To Here(1);
dir = Pick Directory( "Select a directory" );
