Back in the days all the things you would create using the File-menu would be files, because what else would it be???

A benefit of that system was that all documents and data could be easily treated as files - and moved organized as you pleased.

Somewhere along the line someone clearly decided that this was too simple and made storage opaque - and now you never know where anything is stored - and how or where to organize it.

I'm not sure I consider that an improvement.
