Validations on page to provide error/ warning type message when an unsupported or not allowed file type is uploaded. Preventing the user from finishing their task.
There is a file related plugin in the framework already that can be used to move to delete desired files. i.e. a list of file in a particular folder structure that have an unsupported extension.
