Looks at file names in a directory and finds common parts in them trying to search similar and repeated ones. Useful when you have multiple files which differ in checksum and somehow in names. You can collect them and make a decision afterwards.
InfoSpace is an application which indexes and then allows you to search your personal information space, such as your email, your documents, your music, your videos, your Flickr account, your news feeds, the web pages you've visited and much more.
