3.3 File management:
Fundamentals
Files
When you write a part program on the TNC, you must first enter a file
name. The TNC saves the program to the hard disk 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.
