When using GetModuleFileNameEx to query the image path of a running process, some processes have an image path that starts with “\??\”. For example, while most processes start “C:\WINDOWS”, some processes start “\??\C:\WINDOWS”.
What does the leading \??\ mean on a windows path?
It’s a Unicode extended-length pathname – see Naming Files, Paths, and Namespaces in MSDN (the “Maximum Path Length Limitation” section).
(By the way, do you mean
\\?\rather than\??\?)
