If I don't use Path::Class, Win32::Unicode::File cannot survive on it's own. It ends up with Undefined subroutine.... when I call moveW()( How do you know that?? ).

What does that mean?

$ perl -E " use Win32::Unicode::File; use Data::Dump; dd \@Win32::Unic
+ode::File::EXPORT, \&moveW ; moveW()"
(
  [
    "file_type",
    "file_size",
    "copyW",
    "moveW",
    "unlinkW",
    "touchW",
    "renameW",
    "statW",
    "utimeW",
  ],
  sub { ... },
)
Usage: moveW(from, to [, over]) at -e line 1.

And I found the errorW(), dieW() won't work at all. Not sure if I missed something when I download this module via ppm.

You sure?

$ perl -E " use Win32::Unicode;  use Data::Dump; errorW(); dd [ $@, er
+rorW() ]; eval { moveW() };  dd [ $@, errorW()]; eval { moveW(qw{ . .
+ }) };  dd[$@, errorW()]; dieW 666;"
["", "The handle is invalid."]
[
  "Usage: moveW(from, to [, over]) at -e line 1.\n",
  "The handle is invalid.",
]
["", "The handle is invalid."]
666 at -e line 1.

But then, would you point out where absolute() and basename() method import from? I can't find it in the perldoc where the modules you used.

Path::Class gives you Path::Class::File and Path::Class::Dir objects

$ perl -MPath::Class -E " say file(1) "
1

$ perl -MPath::Class -E " say ref file(1) "
Path::Class::File

$ perl -MPath::Class -MData::Dump -E " dd file(1) "
bless({ dir => undef, file => 1, file_spec_class => undef }, "Path::Cl
+ass::File")

$ perl -MPath::Class -E " say file(1)->basename "
1
