.htaccess path on Plesk

[#1]

I am currently rewriting my site to run on Plesk, can anyone tell me what the full path should be for the .htaccess file?
I currently have AuthUserFile /share/isp/plusnet/www/ra/ra****/htdocs/ra****/members/.htpasswd which is working fine but obviously it needs to point to the new account.

/var/www/vhosts/yourusername.plushost.co.uk/httpdocs/etc/etc
or substitute yourdomain for yourusername.plushost.co.uk if appropriate

Thanks a lot Gabe, that works fine.
