This contains the file name extension of the file uploaded. It is directly derived from the RawFilePath property. The file name extension is typically a three character value (e.g. "txt") after the terminating period of a file name - the RawFileType property does not start with a period character.

Depending on the source Operating System and Browser this property may contain characters such as question marks and slashes which are illegal in file names on Windows. It may also contain Unicode characters.
