ISTAP where to put SDP and BLP files?

[martyNZ]

Hi,
This questions is just for my E series coding.

Where do I put the folders DATA and DATA-SWI for ISTAP programming?

I have tried finding this info since days but couldn't. There are many threads and they are all different regarding RHEINGOLD folder, symbolic links, some say put them here c:\ProgramData\BMW\ISPI\data\TRIC\ others say into ISTAD folder, some say into a dedicated folder called PSDZ. I am confused and want to understand how that works.

The PDF ISTA guide says into the ISTAD folder under PSDZ. But how does ISTAP know where to find those files? Do I need ISTAD installed at all for ISTAP? I don't want to use symbolic links. Can I verify before programming with ISTAP that all files are where they supposed to be?

Thanks!
