could you please tell me why I am getting the error below?
readdir returns a list of all directory entries (files, sub-directories, links, etc.), including the current directory, which has the special name '.', and the parent directory, which has the special name '..'.

The 1st open in your while loop tries to open the directory named '.'.

I believe you only want to open files. To do so, use the -f filetest like this: 

use strict;
use warnings;

my $dir = "C:/move/output/test/";
opendir DIR, $dir or die "Unable to open $dir: $!";
while (my $filename=readdir DIR)
{
    my $file = "$dir/$filename";
    next unless -f $file;
    open my $fh, '<', $file or die "Unable to open $file: $!";

Note that I had to prepend the directory name to the filename.
