invalid top dirctory - windows

[SRB]

I get invalid top directory at E:/Perl/lib/File/Find.pm line 562. when i
run this in windows. Can someone explain what I am doing wrong?

use File::Find;
use Win32::File;
use Win32API::File 0.08 qw( :ALL );

my $LogDir = "C:\\";
print $LogDir;

&File::Find::find(\&doFile, $Logdir);

print "done.\n";

sub doFile
{
return unless (-f $_);
print "File: $_ \n";

}
