we just updated SW from 2014 to 2016. It was possible to open files (I call them SW containers) in 2014 format with an ordinary zip program like 7-zip (see attachment). You could see the structure like in a folder tree. That helped a lot to understand this program and sometimes to see, why the files were so big and how the configurations are organized. Files in 2016 format cannot be opened that way anymore. (We skipped 2015, so I don't know how it was there.) Does anyone have clue how to see the structure of 2016 containers?
