Unable to delete cache folder

I ran into a problem and want to delete the AO plugin.

I have deleted it from the plugin directory but unable to delete from cache folder.

There is an htaccess file in wp-content/cache/autoptimize folder that is restricting the deletion.

<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType text/css A30672000
ExpiresByType text/javascript A30672000
ExpiresByType application/javascript A30672000
</IfModule>
<IfModule mod_headers.c>
Header append Cache-Control “public, immutable”
</IfModule>
<IfModule mod_deflate.c>
<FilesMatch “\.(js|css)$”>
SetOutputFilter DEFLATE
</FilesMatch>
</IfModule>
<IfModule mod_authz_core.c>
<Files *.php>
Require all denied
</Files>
</IfModule>
<IfModule !mod_authz_core.c>
<Files *.php>
Order deny,allow
Deny from all
</Files>
</IfModule>

I tried editing and changing the permissions but nothing worked. Please help.
