The new news here is Win32::LongPath, which looks very promising. It was officially released just three months ago, so it wasn't around in 2010 when I asked "Is File::Find Unicode-(Conformant|Compliant|Enabled|Capable)?" It has already been enhanced (just days ago) with an important feature: support for Cygwin. This new CPAN module addresses the problems that I lamented earlier makes Perl—like other modern scripting languages—not generally and dependably useable for folder and file manipulation in the modern Windows environment, including Unicode, long paths and junction/mount points.
Perl scripts written with Win32::LongPath aren't portable, of course. And as far as I can tell, there's no new File::Find::foo module that exploits the new Windows-specific capabilities afforded by Win32::LongPath. But having the ability to manipulate folders and files on Windows reliably using a comprehensive, well-documented and seemingly well-written CPAN module is a big win for Modern Perl versus other scripting languages.
