Hi everyone,
I can solve your puzzle. The files are actually here: C:\Users\<username>\AppData\Local\VirtualStore\Program Files (x86)\EQMOD\PEC
The reason for that: Apps in a modern Windows are not allowed to write data into "Program Files" folder. They should do that into the AppData folder. There are still apps (like EQMOD), that try to write into the wrong folder. Windows is making a virtual folder for them. The app thinks it is writing into the program folder, but actually is redirected into a folder in the app data space, where it belongs.
Cheers, Rainer
