Hi there, If I have a folder that contains the following files:

hsa_circ_0000007.fa.txt_palindromes.csv

hsa_circ_0000008.fa.txt_palindromes.csv

hsa_circ_0000009.fa.txt_palindromes.csv

hsa_circ_0000010.fa.txt_palindromes.csv

And i then use:

my @pal_files = glob("*palindromes.csv");

Am I just feeding the plain names into an array or am I capturing the entire file into the array?

My hunch is that I'm just capturing the name of the file.

How then do I capture all the files with the extension of my choice so that I can then open those files to extract data?

Pete.
