This works fine: 
 use Win32::DirSize;
 open (FILE, "02_dir.txt") || die "can not open file\n";
 chomp (@file = <FILE>);
close FILE;
$f = "d:\\programs";
#foreach $f (@file) {
    dsize($f);
#}

sub dsize {
    chomp (my $param = shift(@_)) ;
    print "$param \n";
    my $Result = dir_size(
    $param,
       my $DirInfo, # this stores the directory information
     );

 
      if ($Result == DS_RESULT_OK) {
       # If you don't want to display results in bytes,
       # let the module determine the best unit.
   
       my $Size = best_convert(
         my $SizeUnit, 
         $DirInfo->{HighSize}, 
         $DirInfo->{LowSize},
       );
       print "Dir size = $Size $SizeUnit \n";
    }
 }

This does not work. 
 use Win32::DirSize;
 open (FILE, "02_dir.txt") || die "can not open file\n";
 chomp (@file = <FILE>);
close FILE;
#$f = "d:\\programs";
foreach $f (@file) {
    dsize($f);
}

sub dsize {
    chomp (my $param = shift(@_)) ;
    print "$param \n";
    my $Result = dir_size(
    $param,
       my $DirInfo, # this stores the directory information
     );

 
      if ($Result == DS_RESULT_OK) {
       # If you don't want to display results in bytes,
       # let the module determine the best unit.
   
       my $Size = best_convert(
         my $SizeUnit, 
         $DirInfo->{HighSize}, 
         $DirInfo->{LowSize},
       );
       print "Dir size = $Size $SizeUnit \n";
    }
