What is the advantage of having htaccess enabled - excuse my ignorance
This is good way to have directory-dependent config for access contol, rewrite engine and so on. It is very usefull for shared hosting, where users have no access to site-wide config.

Hello Diane

IT depends on what you want to use the .htaccess file for ?
