rmtree deletes everything inside the folder but doesn't deletes the root folder him self

Nelly has asked for the wisdom of the Perl Monks concerning the following question:

Hi! I'm trying to move folder that include another folders and files. My actions are:

my $file2Copy = File::NCopy->new(recursive => 1);
$file2Copy->copy($folder,$ArcFolder);
rmtree($folder, 0, 0);
[download]

Every thing is good but it doesn't deletes the root folder that is already empty.

The error message I'm getting is:

Can't remove directory C:\125\Ba_hu\\update35: Permission denied

What is happening? rmtree has deleted everything inside this folder,

but can't delete the root folder that is empty.

I've tried to do:

rmdir $folder;

after rmtree and it's not deleting the folder any way, Please help!!!
