For starters, don't do it like that.
To go up, it would have to proceed the exe file name:
\RAF\bin\Debug\..\..\..\..\RAF.exe
And since an initial backslash means "from the root directory" you can't go up that many levels anyway.
But ... as I said, don't do that. The reason I say that is simple: in production the folder layout will not be the same, or even close. Once installed, you app will be under
Program Files - which isn't necessarily under the root directory of any disk - and the app name. The Debug folder will almost certainly not be available, or probably the bin folder. Instead of "hard wiring" the location and assuming a folder structure that
is unlikely to exist, use a configuration file to store the absolute path to your target EXE and set that when your program first installs.
