The exact format is documented in the online docs, but the best way to get at information inside cart files is to use [OrderFile] and [LineItems] contexts. If you want to test for the existence of any file on your hard disk (regardless of its type), then you can use the new [FileInfo] context in 2.1, or perhaps [ListFiles]Here's an example of getting some information from the order file[OrderFile cart=1234] [Header14], [ShipToState]
[LineItems] [sku], [price]
