- Have a source checkout of Qt Creator v4.2.2.
- Open the project file qtcreator.pro in Creator.
- Wait for project parsing to finish.
- Show the Projects view.
- Expand qtcreator / share / static
- Compare the files you find in "Sources" to those you find in "Other files".
Lots if not all of them are duplicated.
I think each file should be show in only one of these categories.
