I'll try to generate a better example.

I'm using 'dir' in an attempt to glob a filespec and get Unicode filenames, which File::Glob::Windows doesn't seem to do. Will Path::Class do that? I'm using robocopy /l to get the total size of a folder, including subfolders. It's supposed to be a fast way to do that.

I tried using run3, but I don't understand its rules and haven't got it working yet. Is 'hex' a command in your example? Is there a reason that you used short pathnames? Thanks.
