3.3 File Management:
Fundamentals
Files
When you write a part program on the TNC, you must first enter a
program 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.
You can manage an almost unlimited number of files with the TNC.
The available memory is at least 21 GB. A single NC program can be
up to 2 GB in size.

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.
