Data can also be stored in the workpiece directory which is not directly required by the NC for
the machining. In addition to ASCII files, this can be binary files, such as images in JPG format
or descriptions in PDF format. In order that these can be interpreted as binary files by the NC,
the file extensions must be known in the NC (setting during commissioning via MD17000 $MN_
EXTENSIONS_OF_BIN_FILES; the following file extensions are preset in the basic setting:
JPG, GIF, PNG, BMP, PDF, ICO, HTM).
Select workpiece for machining
A workpiece directory can be selected for execution in a channel. If a main program with
the same name or only a single main program (_MPF) is stored in this directory, this is
automatically selected for execution.

External program memory

In addition to the passive file system in the NC, external program memories can also be
available at the machine (e.g. on the local drive or on a network drive).
Using the functions "Execute from external" or "EES (Execution from External Storage)" part
programs can be directly executed from external program memories.

Global part program memory (GDIR)
When declaring the drives, one of the drives can be designated the global part program
memory (GDIR).
The system automatically creates the MPF.DIR, SPF.DIR and WKS.DIR directories on the
drive. These three directories form the GDIR.
The GDIR only plays a role for the EES function. Depending on the drive configuration, the
GDIR replaces or extends the NC part program memory. The creation of a GDIR is, however,
not essential for EES operation.
The directories and files of the GDIR can be addressed in the part program in the same way as
in the passive file system. This permits a compatible transfer of an NC program with path details
from the passive file system to the GDIR. The directory SPF.DIR of the GDIR is contained in the
search path for subprograms.
