Please note that glob is a byzantine way of finding files and it relies heavily on the idea that no part of the glob pattern will contain a space. That idea is prevalent in much of the Unix mindset, but it easily fails on Win32 (unless you start and take care to quote the whitespace).

If you're sure that your paths cannot and will not contain spaces, glob is convenient to use. If there is the possibility that the patterns will contain spaces, I found it more convenient to use File::Find (or File::Find::Rule) right from the start.
