Global part program memory (GDIR)
When declaring the drives, one of the drives can be designated the global part program
memory (GDIR).
References:
Operating Manual; Section: "Managing programs" > "Setting up drives"
The system automatically creates the MPF.DIR, SPF.DIR and WKS.DIR directories on the
drive that acts as the GDIR. 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. However, it is not mandatory to set
up a GDIR for the 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. Therefore, a compatible relocation of an NC program with path
specification is possible for the passive file system to the GDIR.
GDIR replaces the NC part program memory
If the NC part program memory is completely empty in the MPF.DIR, SPF.DIR and WKS.DIR
directories, then the GDIR replaces the NC part program memory. The previous NCK search
path is emulated 1:1 by the GDIR.

2. SPF.DIR in the GDIR memory

GDIR extends the NC part program memory
When the NC part program memory is not empty in the MPF.DIR, SPF.DIR and WKS.DIR
directories, then the search sequence for the subprograms depends on where the main
program is archived (active directory).
Selecting the main program in the NC part program memory (MPF.DIR or xxx.WPD in
WKS.DIR)
Search sequence for the subprograms:
1. Actual directory in the NC part program memory
2. SPF.DIR in the NC part program memory
3. The drive referenced using CALLPATH
