Geocities says,

SUBDIRECTORIES FOR EVERYONE!

If you’ve got a great free GeoCities home page, chances are you’ve got one humongous list of files with image files strewn left and right from here to eternity. Fine—if you have lots of time on your hands. Wish there was a better way? Effective July 17, GeoCities is proud to offer all members subdirectories for building and organizing the structure of their sites. That’s right, subdirectories for everyone—two levels of subdirectories, in fact. Now, all your interests and all your images can have their own little easy-to-find sections. As always, GeoCities is dedicated to giving you the tools you need to create the best home pages. What’s a subdirectory, you say? For more information on how to use subdirectories, read this member’s FAQ http://www.geocities.com/~answerpoint/subdirfaq.html. Now, there’s no excuse not to get organized!
