That's because there's no such filename with quotes in the filename itself. The quotes are used on the Windows command line and similar environments to make sure that Windows knows the spaces are meant as part of the filename, but in a lower-level access like the perl open command, you don't need quotes in the string.

#!/usr/bin/perl
use strict;
use warnings;
my $temp_file = $ENV{'APPDATA'} . '\test file name.tmp';
#$temp_file = '"' . $temp_file . '"'; # not needed, because open() isn
+'t bothered by spaces in the name
print "|$temp_file|\n";
open(my $fh, '>', $temp_file) or die "Error opening $temp_file $!\n";
print "worked!\n";

except for the following ... reserved characters: ...
* " (double quote)
...
... thus indicating that quotes are not part of the filename, because they are not allowed
