I encountered a problem using File::Util.

I am using

My application has to be able to save files to arbitrary drives on my machine (no network drives). So far I can save files on the same drive the script is living in, but when it comes to saving on a different drive it fails: 

File::Util can't use this string for »the name of a file or directory«
+.
   »D:/projects/my_program/TestData/text.txt«
It contains illegal characters.

I know that colons are illegal characters from the error message.
Is it possible to save files to drives other than the one my script is on an how do I specify the path?
Can someone please help me?

Here is an example of what I am trying to do. The test application consists of two buttons only. One for selecting the directory, the other for saving the file.

use strict;
use warnings;
use Tk;
use File::Util;

my $mw            = MainWindow->new();
my $fh            = File::Util->new();
my $directory     = "";
my $browse_button = $mw->Button(
    -text => "Browse",
    -command => sub {
        $directory = $mw->chooseDirectory(
            -mustexist  => "true",
          ),
    },
)->pack();
my $save_button = $mw->Button(
    -text => "Save",
    -command => sub {
        $fh->make_dir( $directory, qw /--if-not-exists/ );
        $fh->write_file(
            file => sprintf( "%s/text.txt", $directory ),
            content => "hello world",
          ); 
    },
)->pack();
MainLoop;
