On Windows, every volume is assigned a unique volume name in the format \\Volume\{GUID}\, where the GUID uniquely identifies that volume. Under certain circumstances described in the “More Information” section, it is possible for a volume to be assigned multiple unique volume names and thus be assigned multiple GUIDs. When this happens, the GetVolumeNameForVolumeMountPoint() Win32 API function will return one of the assigned names, but it may return a name which cannot be used.
