You really shouldn’t have much reason to use GetFolderItem in this fashion. You should only be using paths like this when you are exchanging data with a shell, for example, or when reading a path from a data file.
Again, you don’t need to use any of these path options. I imagine you’re using the ‘find .’ command from a shell. You could just as easily write a small algorithm to step the directory tree using FolderItem. I think you’d find this to be pretty darn fast and convenient.
