Ever had trouble locating that httpd.conf file? Spotlight is of no help there. I've just released a free app called FindAnyFile that can help with this, as it can find any file on local Mac discs. It doesn't rely on a database like the locate command and Spotlight do, but instead uses the Mac OS operations for searching an entire disk on demand. Furthermore, it can run as root user (provided you know the admin password), allowing it find really any file existing on the disk.
If you end up with 100s of hits, you'll appreciate the new Folder View which shows you a hierarchical list of the folders in which the found items appear. Finally, you can save your searches and reopen them later again for convenience.
[robg adds: I tested this, and it worked quite well for finding those deeply-buried files that are ignored by Spotlight, or not found due to an out-of-date locate database. Since it's a free app, I felt it worth sharing here.]
