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 name
PROG20
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. Table names must start with a
letter.
The maximum permitted path length is 255
characters. All drive characters, directory and the file
name, including the extension, must not exceed 255
characters.
