3.4 Working with the file manager
Directories
To ensure that you can easily find your files, we recommend
that you organize your hard disk into directories. You can divide a
directory into further directories, which are called subdirectories.
With the –/+ key or ENT you can show or hide the subdirectories.
Paths
A path indicates the drive and all directories and subdirectories
under which a file is saved. The individual names are separated by a
backslash "\".
The path, including all drive characters, directory
and the file name, including the extension, must not
exceed 82 characters!
Drive designations must not include more than 8
uppercase letters.
Example
The directory AUFTR1 was created on the TNC:\ drive. Then, in the
AUFTR1 directory, the subdirectory NCPROG was created and the
part program
PROG1.H was copied into it. The part program now
has the following path:
TNC:\AUFTR1\NCPROG\PROG1.H
The chart at right illustrates an example of a directory display with
different paths.
