Using `"$dir/$_"` changes your paths from relative to absolute. Unless your working directory (the directory your shell was in when you executed perl) is equal to `$dir`, -d will be looking in the wrong place. This might be more obvious if you execute the code: `#!/usr/bin/perl use strict; use warnings; use 5.10.0; my $dir = "C:/Users/ST/DesktopSample"; opendir (my $gdh, $dir) or die "Unable to open main directory"; say for readdir($gdh); closedir($gdh);` [download] #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply] [d/l] [select]

"$dir/$_"

$dir

#!/usr/bin/perl
use strict;
use warnings;
use 5.10.0;

my $dir = "C:/Users/ST/DesktopSample"; 
opendir (my $gdh, $dir) or die "Unable to open main directory";
say for readdir($gdh);
closedir($gdh);
