A dcf is a Design corner file, whereas a pcf is a Process corner file. In reality the contents are the same - but if a pcf file is loaded, you can't change it, but anything loaded from a dcf file is editable.
In IC5141 you can Print the measurements, and then do Window->Print and save to a file. It's not CSV, but it's something you could hack into CSV.
In ADE XL in IC61X, you can certainly export to CSV or HTML.
