Next, goto you Domain Manager and direct your domain name to point to that folder. That way, they do not need to add the folder extension in the web address to get to your front page.
Using hosting accounts, it is usually wise to install websites or other components into sub-folders. If you ever want to run more than one website from the same account, they definitely need to be in separate folders. If you ever want to run other, non-related, software such as forum software, they also need to be installed into a separate folder.
One might organize their hosting service like below:
*ROOT*
/jones_com
/jones_net
/war_novels_com
/billing_service_com
/smforum
/coppermine
With the above example, I demonstrated a hosting account file-structure using three web-addresses and two ancillary software titles.
Websites in the above example:
www.jones.com
www.jones.net
www.war-novels.com
www.billingservices.com
Ancillary software packages:
/smforum = simplemachines forum software
/coppermine = coppermine photo gallery software
Notice that the web-addresses do not have to exactly match the folder name, but the folder name should have some resemblance of what it contains (only for organization and memory reasons). I can now go into my Domain Manager and point any "owned" domain name to any of these folders. So, for example, I can type-in
www.jones.com
and the browser will be pointed automatically to the /jones_com sub-folder.
(NOTE - the reason I put the _com after the folder is in case you also own the .net variation of the same site and want different software to be ran from inside that specific folder)
(ANOTHER VARIATION - I personally own .com and .net variations of the same domain name and I have both variations pointing to the same folder).
I hope this helps!
