Find In Files is a application that searches a set of files (or all files) for some text. It is available for 68K and PPC. Here is an example. Suppose you have 100's of Microsoft Word files, and one or more of them has some information you need. You could open every one of the files and search them by hand, or use Find In Files to search for you. Simply enter some key words, enter the creator and file types (or click the Select File button, and open any file to get the creator and file type), enter the folder where the search should begin, and click on Search. Find In Files returns with a list of text snippets and the files that contain the text snippets.
