How to block access to files from the browser?

Question

htaccess

I was able to block access to one file using .htaccess

<Files 1.txt>
Deny from all
</Files>

and how to close access to 3 files in one directory?
Thank you!

Answer 1

<FilesMatch ^(1\.txt|2\.txt|3\.txt)$>
Deny from all
</FilesMatch>

Through mod_rewrite - the easiest way.

RewriteEngine on 
RewriteRule (1\.txt|2\.txt|3\.txt)$ - [F]
