Thanks for your feedback. The DFP documentation will be changing soon, but since the functionality is still the same (only the access points have changed), everything there should work for customers who are using Universal Email 4 or Digital File Pro.
You're comment on A - Z documentation for using our suites is noted and something we are working to fulfill. In many cases, this is something we hope to fulfill with better products as well as more documentation. Our tools do so much, there could never be one tutorial for how to use all of them, because they can be used for so many different applications.
If you are referring to PowerStore, this is currently not a feature of the product, and not documented. However, some other users here in the forums have worked out ways to migrate a CSV file to their PowerStore database, which might help you.
