Note: in the following examples, that is the only place where the locks occur, it's not being locked from multiple places, but the static method may be called from multiple threa...
If I have a file path like "C:\My Documents\Images\Image1.png", how can I get the parent folder name of the "Image1.png" file? In this case, "Images", but that's just a sample.
