What is the value of $file_path when you pass it as an argument to mkpath? To find out, insert the following statement in your code immediately before the statement that calls mkpath. print "Here is the path name to pass to mkpath:\n$path_name\n";#For debugging only Also I recommend that you include the statements

use strict;
use warnings;

at the beginning of your script and then fix the warnings and error messages that result from the strict and warnings modules.
