Can't Delete Programs

I can't find a way to delete programs in heidenhain millplus v320. The instruction manual just tells to go to program tab then press menu and select remove program. But I when I go to the menu I don't have that option the menu looks different there is only the possibility to choose a program.

Attached are photos of the manual and what my menu looks like.

Use the control tab / menu for file options.

yes.
control tab -> Menu -> file editor
In File directory , programs list will be displayed
you will have delete soft key in the screen.
