Abstract: A key code generating engine strips extenders and other unwanted characters from a file or product name, truncates the remainder to a set maximum, appends the result to an identifier and provides a version suffix. The key code then is associated with other information about the file or product, such as a description, version, size, and a location identifier such as an address, telephone number or Internet web site URL. The resulting record is collated into a plurality of databases accessible through the Internet and searchable by key code or boolean keyword strings to locate files for downloading or vendors' web pages for ordering or learning more about a product. Multiple database systems segregated by subject matter can provide users a virtual card catalog of products and their respective upgrades, patches and add-ons.
