 * The upgrade files include the following instruction:
 * Before you upgrade anything, make sure you have backup copies of any files you
   may have modified such as index.php.
    Upgrading from any previous WordPress to
   2.8:
 *  1. Delete your old WP files, saving ones you’ve modified.
 * I have inspected my WP files on the server and there is no way I can see of telling
   which files I have modified since there are no file dates shown.
    How do I know
   which files they are……or am I missing something…..apart from a deep knowledge
   of the subject?

 * That is usually for few of those who hack core files for their installation. 
   Most probably you didn’t touch those (since you don’t remember) so just delete
   the files — P.S. DO NOT DELETE wp-config.php and htaccess in root

 * Sounds simple doesn’t it. So if I delete
    -  all
 *  the files except wp-config.php and htaccess then I will not lose any of the 
   information and published articles in my blog? Is that what you are saying? Does
   this include the WP-admin/content/includes folders? Seems to me if I delete ALL
   files I will be starting from scratch! Can you elucidate a little further?
    Thanks.

 * **BACKUP** Database, wp-content folder (which includes your themes, plugins and
   uploads folders), wp-config.php and htaccess
 * Then delete wp-includes folder and wp-admin folder and upload whole WP-2.8
