There are a lot of ways to do it. You only want the check boxes, so what I would do is first check to make sure all my checkboxes have the same name and then store them in an array like this:

#! Perl -w
use strict;
use CGI;
my $q = new CGI;
my @checkbxs = $q->param('the_name'); # only those that are checked en
+d up in here

for (@checkbxs) {
    &delete_file($_); # assuming a delete sub exists
}
