File names
When you store programs, tables and texts as files, the TNC adds an
extension to the file name, separated by a point. This extension
indicates the file type.
File names should not exceed 25 characters, otherwise the TNC
cannot display the entire file name.
File names on the TNC must comply with this standard: The Open
Group Base Specifications Issue 6 IEEE Std 1003.1, 2004 Edition
(Posix-Standard). Accordingly, the file names may include the
characters below:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i
j k l m n o p q r s t u v w x y z 0 1 2 3 4 5 6 7 8 9 . _ -
You should not use any other characters in file names in order to
prevent any file transfer problems.
Data backup
We recommend saving newly written programs and files on a PC at
regular intervals.
The TNCremoNT data transmission freeware from HEIDENHAIN is a
simple and convenient method for backing up data stored on the TNC.
You additionally need a data medium on which all machine-specific
data, such as the PLC program, machine parameters, etc., are stored.
Ask your machine manufacturer for assistance, if necessary.

File name File type
The maximum limit for the path and file name together is
82 characters (see "Paths" on page 120).
Saving the contents of the entire hard disk (>2 GB) can
take up to several hours. In this case, it is a good idea to
save the data outside of work hours, e.g. during the night.
Take the time occasionally to delete any unneeded files so
that the TNC always has enough hard-disk space for
system files (such as the tool table).
Depending on operating conditions (e.g., vibration load),
hard disks generally have a higher failure rate after three to
five years of service. HEIDENHAIN therefore
recommends having the hard disk inspected after three to
five years.
