To ensure that student submissions get processed without error, here are D2L submission guidelines:
Students must be sure that filenames for the files they are submitting do not contain any of the following special characters, or D2L will not allow the file submission:
! " # $ % & ' ( ) * + , / : ; < = > ? @ [ \ ] ^ ` { | } ~
Filenames must include the extension, which is one dot followed by the file extension. (More than one dot, such as filename..doxc, will throw an error.)
Although any file size is accepted, there is one exception: If the Turnitin feature is enabled for any given submission, the file limit size for that submission is 40 MB.
