htaccess redirect subfolder to root - apache

Question

This has been frustrating me and I can't find the same issue, maybe I am just searching wrong. Someone messed up and we have a bunch of Google links to a subfolder that does not exist. So I am trying to do a 301 redirect in htaccess to sort that out.
The problem is I can't seem to get the redirect to work more than one folder deep.
Example. http://example.com/subfolder/someOtherFolder redirects to http://example.com/someOtherFolder just fine.
However http://example.com/subfolder/someOtherFolder/yetAnother stays on the same page and returns a 404.
This is the last variation of my entire .htaccess that returns the above results, nothing I've tried has returned anything but the above.
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
RewriteRule ^sitefiles/(.*)/$ /$1 [R=301]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php
</IfModule>
Help? (I hate .htaccess >.<)

Answer 1

The problem is with this rule:
RewriteRule ^sitefiles/(.*)/$ /$1 [R=301]
This rule required a trailing slash on the requested URI
Instead:
RewriteRule ^sitefiles/(.*) /$1 [R=301]
Note that there's also a Redirect directive to do simple Redirects. In your case:
Redirect /sitefiles /
Finally, note that the entirety of that Rewrite block can be replaced with:
FallbackResource /index.php
Thus, the final recommended (best practice) configuration would be:
Redirect /sitefiles /
FallbackResource /index.php
Rather than using Rewrite at all.
