To: gleeaikinYou can find a freely available tool called agent ransack that will do recursive searches of text within files of directories and sub-directories. Provided your files are pdfs word processing docs, html files or the like as well as plain text, it works quite well and is easy to use. You can search the whole drive, specific directories, multiple locations, specific file types and you can also use regular expressions as well as using the wizards to help create search syntax for you and you can save your searches for reuse.
