And even without advanced analysis, a lot can be done. The OS already saves the date when a file was created/edited - which could be used to sort results by date or to search for files that were stored at a certain date. File types are also trivial to determine. It could save some more info, like which application created it, or which website a file was downloaded from, or where it was copied from (usb stick / digital camera / ...). Some file formats have their own information tags as well, for example, an mp3 file knows the album and author - things a good search engine could work on. I agree with you, Jim. Naming files and putting them in the right folders shouldn't be necessary. Even though there are people that organize their files, there are far more which don't. And it would be great if we didn't have to.
