4.2 File Management
Files and file management
When you write a part program on the TNC, you must first enter a
file name. The TNC then stores the program as a file with the same
name. You can also store tables as files.
File names
The name of a file can have up to 8 characters. The special
characters @, $, _, %, # and & are permitted. When you store
programs and tables as files, the TNC adds an extension to the file
name, separated by a point. This extension identifies the file type
(see table at right).
PROG20 .H
File name File type
The TNC permits only one file type per file name. You
cannot assign several file types to the same name.
The TNC can manage up to 64 files. Their total size, however, must
not exceed 256 KB.
Working with the file manager
This section informs you about the meaning of the individual
screen information, and describes how to select files and
directories. If you are not yet familiar with the TNC file manager, we
recommend that you read this section completely and test the
individual functions on your TNC.

Press the PGM MGT key:
the TNC displays the file management window
The window shows you all of the files that are stored in the TNC.
