Wordpress Htaccess - stop subdirectory auto redirecting to root index

Question

I'm trying to make a subdirectory on wordpress

http://wpsite.com/codeigniter, http://wpsite.com/someothersubdir

But when I go to that url, it always redirects back to the wordpress site with the "page not found"

Here is the wordpress root htaccess file

# -FrontPage-
IndexIgnore .htaccess */.??* *~ *# */HEADER* */README* */_vti*
<Limit GET POST>
order deny,allow
deny from all
allow from all
</Limit>
<Limit PUT DELETE>
order deny,allow
deny from all
</Limit>

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

How can I make sub directories separate from wordpress? Thank you
