That's a different situation. That's because the operating system's CAN'T run some types of files, and developing something for all can sometimes be too much work that it isn't attempted.

Also, on PTC an OS is really just a GUI, an alternative for launching other programs, not technically an operating system, which would manage the applications that are running, whereas on PTC it cancels its own process and gives complete control to whatever program is executed after it.
