Personally, I'd never use File::Find where glob does the job. The need for the sophistication and overhead of F::F is less on win32 where you don't have links and most other forms of pseudofiles to deal with.

I like the fact that glob does a large amount of the work of pre-filtering of names before it gives me anything.

I also infinitely prefer it's iterator form over any callback style function.

And finally, I like that I can give it either a relative or absolute path plus wildcard and it will give me back the same type of paths, which most times is exactly what I want. Even when traversing subdirectory trees, I prefer to decide which directories to decend into, and in which order, at the point of use rather than stacking up large arrays. It uses less memory, and means I can abort or restart a search part way through if needed--something that is near impossible with the callback style of interface.

In fact, I can honestly say that I have no code, beyond my initial, aborted experiments, that uses File::Find, or any of the other callbacks+globals, style of doing things. YMMV :)
