The FileUpload component does not parse the file name. It provides to its
client exactly what the browser provides to it. Unfortunately, different
browsers behave differently - some provide the full path, while others
provide only the file name. If you want to use the same file name on the
server that the client provided (not recommended, for security reasons
amongst others), you'll need to parse out the base file name when the
browser provides the path as well.
