Summary of Problem: You are converting the wrong data

Desk checking your code, I suspected I understood the error. So I modified your code to show what you are actually asking the rename to do, and it was as expected: You are trying to rename the file to the same name it already has: 

use File::Find;
use File::Basename;
use File::Spec;
use strict;

find ({ 'wanted' => \&renamefile }, 'c:\\folder1\\folder2');

sub renamefile {
    my $file = $_;
    return unless (-f $file);
    my $dirname = dirname($file);
    my $file_name = basename($file);
    my $new_file_name = $file_name;
    $new_file_name =~ s/\\\\/./g;

    print "\$file = [$file]\n";

    my $resulting_filename = File::Spec->catfile($dirname,$new_file_na
+me);
    print "\$resulting_filename = [$resulting_filename]\n";

    rename($file,File::Spec->catfile($dirname,$new_file_name))or die;
}

$file = [abc.txt]
$resulting_filename = [abc.txt]

Bottom line: You are supplying the unqualified filename and asking it to change all the backslashes (which by definition there are none) to dots.

Since there are no backslashes in an unqualified filename, you get back the same name you supplied.
