It may have been posted already, but just to share my findings. It can be useful in some cases.
After processing vehicle, ISTA/P generates the same files as in work folder of NCS Expert, FSW_PSW.TRC, NETTODAT.TRC, INDIVID.TRC etc.

It seems that if vehicle is just read it will generate all files except FSW_PSW.TRC.
After accepting measures plan and processing it will generate FSW_PSW.TRC

Location of folder: C:\ProgramData\BMW\ISPI\data\TRIC\ISTA-P\BMW\Services\data\ecudata\chassis folder\work

I don't have ISTA+ with programming enabled, but I assume that ISTA+ also generates these files. Maybe someone can check what and in which cases it is generated.

ISTA 4 cannot program Exx models, only F,G,I.
Therefore, as you know, you cannot use NCS on these models, and so there
will not be the same files generated using ISTA to program these cars.

Nice find though!
