make a copy of database

Hi:

I have installed sql server 2005 express and SQL Server Management Studio Express

How can I generate a database from another copying the structure and data?

For example I have a database named Customers, I need to make a copy of Customers named Customers2. Customers2 also will be attached to the same Database Engine Server where Customers is attached.

How I Can do it?

Thanks!

P.S.

I tryied to make a copy of mdf an ldf files from Windows Explorer and renamed these files but I could not attach to the same Database Engine Server because I got an error.

The easiest way to do it is with the Backup and Restore Wizard because during restore you can change the name of the new one to customer2, I do it all the time, email the .bak or restore the .bak with a new name for a different department. If you don't have the SQL Server Express Advanced download it from the link below to use the Backup and Restore Wizard. Hope this helps.
