Locate32 - for very fast searches of specific directories

Locate32 is a free tool that allows you to create custom search database files for a nominated directory (including network resources and USB storage).

You can then manually update these database files when you want to do a fast search.

It is very quick to index the files and the search results pane is very fast and functional.  I have used it in the past to delete or archive Revit backup files.
