in reply to Tk::DirTree & Win

To solve similar problem, I add following lines into my code: 
  if ($^O eq 'MSWin32') {
    require 'Win32API::File';
    my @drv = map{s/\\$//;lc} Win32API::File::getLogicalDrives();
    $dt->add_to_tree($_, $_) for @drv;
  }

[download]
where my $dt = $dirlist->Scrolled('DirTree',....

Also, to behave good on Win32, I override 'has_subdir': 

package Tk;
sub has_subdir {1}

[download]
and you will not get annoying behaviour, when before opening a window each drive will be tryed to access, causing by CD-ROM, diskette to roll, and slow network drives to slow down your program.

Warmest wishes,
Vadim

    correction: I override 'has_subdir' in Tk::DirTree package.
    Also there is some more to override in those packages for Win32 (for case-insensistive sorting, for exampe): 
    package ::Tk::DirTree;
sub has_subdir {1}
sub DirCmd {
    my ($w, $dir, undef) = @_;
    $dir =~ s/^(\w:)$/$1\//;
    my $h = DirHandle->new($dir) or return;
    my @names = grep( $_ ne '.' && $_ ne '..', $h->read );
    return @names;
}
sub add_to_tree {
    my( $w, $dir, $name, $parent ) = @_;

    my $image = $w->Getimage( $w->cget('-image') );
    my $mode = 'none';
    $mode = 'open' if $w->has_subdir( $dir );

    my @args = (-image => $image, -text => $name);
    if( $parent ) {             # Add in alphabetical order.
        foreach my $sib ($w->infoChildren( $parent )) {
            if( lc($sib) gt lc($dir) ) {
                push @args, (-before => $sib);
                last;
            }
        }
    }

    $w->add( $dir, @args );
    $w->setmode( $dir, $mode );
}
