How to change the site access root in .htaccess?

Question

Yii

Help! We need to change the way the site works.
Yii engine. .htaccess file content
AddDefaultCharset utf-8
# Universal redirect from C domain www. to a domain WITHOUT www
# if necessary - uncomment:
#
# RewriteCond %{HTTPS} !=on
# RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
# RewriteRule ^(.*)$ http:// %1/$1 [R=301,L]
# prevent httpd from serving dotfiles (.htaccess, .svn, .git, etc.)
RedirectMatch 403 /\..*$
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule . index.php
When you enter the site address, a list of files and folders on the hosting appears. The site itself is located in the /public/index.php folder.
How can I make sure that when entering the site url, the start (main) page opens and not the list of folders and files?
Help me please!

Try this
# RewriteCond %{HTTPS} !=on
# RewriteCond %{HTTP_HOST} ^www/.(.+)$ [NC]
# RewriteRule ^(.*)$ http://%1/$1 [R=301, L]
# prevent httpd from serving dotfiles (.htaccess, .svn, .git, etc.)
RedirectMatch 403 /\..*$
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule *. index.php
