Why can’t I access my files it say something is turned off or not installed?

The only thing I can think of without seeing the device is that one of the main programs that utilizes whatever you’re are attempting to open is disabled OR needs to be updated in the play store. If you go to settings > applications> and look for the disabled and/or check for a software update, check the play store for application updates that may run the file you’re attempting to open. The only application I can think of for the S5 is either called Memo/Notes.
