I'm not sure what you are asking.
It sounds like you are asking for Console/DOS commands, but, I'm not sure what you mean.
If that is the case, then that really has nothing to do with C++.
If I'm wrong, then: "\\blahblah\\" is the exact path to whatever folder or directory and file you are looking for.
Do you know the filename you are looking for and its path from the "root" ?
ie: "C:\myfolder\myfile.exe"
