The benefits of the indexing method employed by Paper Tiger are many. The first is security. Because your files are numbered, it makes it difficult for people who are unauthorized to see confidential information.
Secondly, you can setup ALL of the hanging file folders ahead of time (the software ships with over 300 pre-printed tabs) so actual filing is very easy.
Finally, most users of Paper Tiger keep a printed report of the contents of their file cabinet (printed in alphabetical order by main item name) handy for quick reference and in case their computer is temporarily out of service.
