We can define stem and extension in different ways:
1 - stem can be empty, and extension is the part after the last dot.
2 - stem can not be empty, and extension is the part after the last dot after the first character (ensures stem it is not empty) or the part after the first dot after the first character.
3 - stem and extension are not empty and have a sens only when the filename follows the pattern "stem"."extension". For all the other stem and extension is undefined (an exception cn be throw in this cases).

Note that there are other files (. and ..) which have not evident stem or extension. Have you considered the 3rd alternative?
