How to crawl folders to index files?
<p>Im working on a script that is going to find all *.R3D from a certain folder tree and index them. I have seen many examples on how best to crawl through folders and subfolders, but they don't seem to pretty, and since im working on a server i want to keep load as small as possible.</p>

<p>My questions: I want to find the most effective way crawl through folders and subfolders to index/find a certain filetype.</p>
