SoftFile protected from copy&paste and ScreenCopy on PC

   When SoftFile shows its contents as Process, it starts up another Controll Object(as another Process). If Controll Object works ,The Process ,that is SoftFile shows all contents. If not ,The Process ,that is SoftFile shows only 1st page , hide other contents. (see fig.2 dot line circle A) This Controll Object(another Process) keep clearing ClipBoard and undoing key Input cotinuouly. (see fig.3)

The Process ,that is SoftFile shows its contents ,

keep observing that Controll Object(another Process) is aliveby checking copy&Paste something itself. (see fig.2 dot line circle B) If copy&Paste something is enable ,it means Controll Object(another Process) doesn't work. Then The Process ,that is SoftFile shows its contents, close itself by itself. (see fig.2 dot line circle C)
