301 redirect mask in htaccess?

Question

htaccess

Good
afternoon The site on Joomla was hacked and doorways were flooded into the folders at the root.
All this was included in the PS index.
The pages of the doorway have been gone for a long time for new VMs, they weigh like a 404 error
.
I did not find a ready-made solution in the PS.
The folder name can be used as a mask.
URL example domen.ru/informatika/id-number308.html

RewriteCond %{REQUEST_URI}?%{QUERY_STRING} "\/informatika\/.*?$"
RewriteRule ^(.*)$ /glavnaya/files? [R=301,L]
