Settings / Settings | Editor | General | Using paperbacks in the editor - this option affects all files.
You can disable or enable this option for each file (before it is closed) through View | Active Editor | Using soft wrappers
A later version (compared to the versions available after answering this question) also contains these options in the "Reservoir of the Editor" menu (right-click in the area where line numbers / breakpoints / etc. are indicated).
PS
The settings screen has a very nice feature - a quick search window (upper left corner) - it works wonders. This allows you to quickly narrow down your search to a specific parameter by name (keyword).
You can also use "Search anywhere" ( Shift twice), as well as "Find action" ( Help | Find Action... Ctrl + Shift + A ) to search for individual settings.
