How to access directory .htaccess issue

Hi, I am using an .htaccess file as follows:

Options -indexes 
DirectoryIndex index.php 
RewriteEngine On 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index.php|images|javascript|style|robots.txt|user_guide) 
RewriteRule ^(.*)$ /dof/index.php?/$1/ [L]

Code (markup):

I don't know much in .htaccess. I am facing problem to access a directory named 'user_guide'. What modification I should do to get the access of that directory?

Regards

 

Try

RewriteCond $1 !^(index.php|images|javascript|style|robots.txt)
