Where are 'File Sharing' files stored on the server?

[Garindan]

Just wondered if anyone knew where files uploaded through the panel to file sharing are actually stored on the server? I couldn't seem to find them anywhere.

Also, if I send out a html email should I store the images etc in the plesk public file sharing? I had been storing them in http docs image folder, but have just started using plesk panel file sharing and wondered if this was a better option?

Many thanks.
