The Alteration Guide describes creating custom screen files without page numbers that all screens load by default.
The Fuel and Engine screens are common to most pages.
I currently have to create Engine1.sdf, Engine2.sdf, Engine3.sdf, etc as all identical copies.
I have tried creating screen files titled Engine.sdf, E.sdf, Engine0,sdf, EngineX.sfd, without success.

Has anyone been successful in creating Global Screen files that are loaded by default on all pages?
What file names did you use?

This is intended for the creation of a dfile system - this is a virtual file system you create from your defaults folder (filled with epd files - the default screen files). The last group of functions in your screen designer is dedicated to this - have a look at your defaults folder and the filenames the designer creates for your various selected options.
Once done - you then package your creation into a single dfile which then gets installed into the target device screens folder. If this is found when the EFIS starts up it completely forgets about it's internal built in screen files and uses the dfile instead. Note that it is limited to a total of 256 files (more than enough for most).

You can create a large number of layouts for different applications that the user can select from - the EFIS menu system will adapt itself to your dfile for screen selections.

Thanks, Rainier,
I missed the part where this was only applicable to the Default File System.
