Programming Tips and Gotchas

• GetExtensionName is a string parsing method rather than a filesystem method. It does not verify that Path is valid, does not verify that the filename designated in Path exists, and does not even guarantee that the value it returns is a valid file extension. In other words, GetExtensionName has no intelligence. It simply parses a string and returns the text that follows the last dot of the last element.

• Path can be a network drive or share.
