multiple stores (files) one database

it is possible to install multiple stores (files) in different domains and subdomains and use the same database?

Yes. Multi-store is supported by nopCommerce - http://docs.nopcommerce.com/display/en/Setting+up+Multiple-Store

Yes. NopCommerce is fully multistore.

Thanks for answering, most do not think you understand my question, to install the files by in various domains and subdomains,
SITEA - upload files
SiteB - upload files
SiteC - File Upload
and the same and use of database SITEA

I could not configure the Multi-store format, I'm using PLESK 11.5, follow the steps in the forum, more ianda could not.

thanks again!
