Getting a directory name from a filename

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?

Solution

  • 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.
