Heidenhain ManualPlus 4110 - GTI and GTZ files - cycles and outlines

[grzeniua]

Hello,
I have a following question: in which way can I transfer the files from Heidenhain ManualPlus 4110 to my laptop so I can view the files written in cycles and outlines with all parameters (files extensions: *.gtz & *.gti). Is there any free software, which reads gti & gtz files?? It's very desired, because in this way I could modify some program "at the desk" and not to stay all time at the machine, and the machine must be energized for all the time...
I'm able to move files from NCPS folder but those are in G-codes, and if I view the files *.gti & *.gtz, they are not "readable".
Programs in cycles could be of course converted into G-codes but it's not a solution - I'd like to edit cycles (with outlines) programs and simulate them externally and then move them to machine control and eventually insert some corrections if needed.

Thank you in advance for the feedback,
regards, Greg
