How to Install WordPress in Its Own Directory in WordPress 2.9

1. Open the root folder on your server. This may be 'www' or 'public_html.'
2. Create a new folder on the server. For these example, we will name ours 'WordPressFolder.'

3. Log into your WordPress site through your Web browser.
4. Click 'General' under 'Settings.'
5. Change the site address next to 'WordPress Address' (uniform resource locator) to your new folder. For instance, if the link was 'http://www.mysite.com,' make it 'http://www.mysite.com/wordpressfolder/.'
6. Enter your root address next to 'Site Address,' for instance 'http://www.mysite.com.' It may be there already.
7. Click 'Save Changes.'
8. Move the three WordPress folders on your sever (wp-admin, wp-content, wp-includes) into your new WordPress folder (WordPressFolder).
9. Copy the 'index.php' and '.htaccess' files into the WordPress folder. You will now have two copies, one in the original root location and one in the new folder.
10. Open the original 'index.php' file.
11. Change this phrase 'require('./wp-blog-header.php');' to, in our example, 'require('./wordpressfolder/wp-blog-header.php');'. Select 'Save' when finished.
12. Log in to your WordPress account from the new location. Instead of 'http://www.mysite.com/wp-admin', it will now be 'http://www.mysite.com/wordpressfolder/wp-admin'.
