When you write a part program on the TNC, you must first enter a
program name. The TNC saves the program to the internal memory
as a file with the same name. The TNC can also save texts and
tables as files.
The TNC provides a special file management window in which
you can easily find and manage your files. Here you can call, copy,
rename and erase files.
With the TNC you can manage and save files up to a total size of
2 GB.
Depending on the setting, the TNC generates a
backup file (*.bak) after editing and saving of NC
programs. This can reduce the memory space
available to you.
