When you run the 2008 SQL Server Import and Export Wizard from SQL Server Management Studio, you have the option of saving the package to the SQL Server msdb database or to the File System.
To access a package saved to the msdb database or to the File System, open SQL Server Management Studio and connect to Integration Services. Then, expand the Stored Packages node. For more information, see Managing Packages at http://msdn.microsoft.com/en-us/library/ms137916.aspx
