❌ Not Working: .htaccess redirect FROM subfolder to domain name

RewriteRule ^subfolder/(.*)$ /$1 [R=301,L]
✅ Working: .htaccess redirect entire subdomain "/subdomain/" and files "/subdomain/file_01.php" within are redirected to domain name "example.com"
RewriteEngine on
RewriteRule ^subfolder/.*$ / [R=301,L]
