KDS only handles .asm and .S as valid assembly code files, and the preference is locked and can't be modified or added
(Preference -> General -> Content Types -> Text -> Assembly Source File).
For the projects I'm working on, all assembly files are in .s postfix instead of .S, and KDS just simply ignore them.
Is there a way to add .s support?
Is this a feature or defect?
Only Linux is in real case-sensitive file system, both Windows and OS X (can be case sensitive, but the home drive normally isn't setup that way) are case aware, but not case sensitive.
