SQl Syntax --Quotename

I am trying to add a linked server name customer to get this
customer.Addresses.dbo.sysfiles from code below
@name = databasename => addresses inthis example
customer   = linked server
Addresses  = databasename

--code

select @SQL = 'insert into #databases
                        select N'''+ @name + ''', sum(size) from '
                        + QuoteName(@name) + '.dbo.sysfiles'


Any ideas ,  also can someone explain to me what Quotename actually does?

It returns the stringwith valid SQL identifier. i.e. adds '[' or ']' to string if required.

To add your linked server name just simply add it :-) :

select @SQL = 'insert into #databases
                        select N'''+ @name + ''', sum(size) from customer.'
                        + QuoteName(@name) + '.dbo.sysfiles'

QUOTENAME allows you to surround a string of length up to 128 characters (which can include white characters like spaces) with brackets (by default) or any other characters you want.

Example:

SELECT QUOTENAME('this is my string')

Result:

[this is my string]

This  function is useful when you want to make sure that your non-standard identifiers (nonstandard object names - those names which consists of not only alphanumeric characters) will not cause any errors in SQL statements. In your example no matter what will the name of the database be, the query should run properly.
