Ew. map in void context. Hand rolled directory traversal (though that's not as bad on Win32). How about 
use File::Find;
my $size;
find(sub { $size += -s _ if -f }, $TargetPath);

(Yes, File::Find is slower than hand rolled traversal. A heck of a lot less (and clearer) code, though, and still beats the dir /s approach by miles.)

Makeshifts last the longest.
