Hi.
How can I enter path to ‘system32’ correctly?
I’m using EngMapFile function and I want to pass this path to this function.
I tried to pass
L"%SystemRoot%\System32\data.dat" and
L"\??\%SystemRoot%\System32\dat.dat"
but this function just returns a NULL parameter in this case.

L"\SystemRoot\System32\data.dat"

Thank you.
