I have a filename (C:\folder\foo.txt) and I need to retrieve the folder name (C:\folder) in C++. In C# I would do something like this:
string folder = new FileInfo("C:\folder\foo.txt").DirectoryName;
Is there a function that can be used in C++ to extract the path from the filename?
There is a standard Windows function for this, PathRemoveFileSpec. If you only support Windows 8 and later, it is highly recommended to use PathCchRemoveFileSpec instead. Among other improvements, it is no longer limited to
MAX_PATH(260) characters.
