I'm following the upgrade tutorial and it says
Delete these Files and Folders:
* wp-* (except for those above), readme.html, wp.php, xmlrpc.php, and license.txt; files; Typically files in your root or wordpress folder. Again, don't delete the wp-config.php file.
What is wp-*? Does that mean every file that starts with "wp" besides the ones that it says NOT to delete?
