To traverse a directory tree and do stuff with some or all of the data files therein, this method works very fast, takes up very little memory, and is a relatively easy framework for handling lots of jobs of this ilk.

If you really don't like the interface of File::Find, try my File::Finder, which is essentially find implemented in Perl.
