By default WordPress considers all files and directories from the installed directory to be under its control.
For a website I had installed WordPress in the root of the website file structure.
Subsequently I wished to install another program suite within a subdirectory.
I had no desire for files missing within this directory to be reported as a WordPress website 404 error.
To exclude the subdirectory called gallery from the WordPress website I added a rewrite condition to the .htaccess file within the root of the website.
RewriteCond %{REQUEST_URI} !^/?gallery
Giving:
# BEGIN WordPress
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/gallery
RewriteRule . /index.php [L]
# END WordPress
With the addition of an additional RewriteCond statement I was able to exclude a subdirectory from inclusion in the existing WordPress website.
