An instructor has pointed out to me that files he has uploaded as PPS
(PowerPoint shows)are returned to users as PPT files when they click save
target as. This enables them to edit the files in powerpoint which is what
the instructor sought to avoid by using PPS.
The odd thing is that when I upload the same PPS to my own website and
download it, only a PPS is returned. This suggests to me that this is
something to do with the way blackboard handles the file. I have raised a
ticket with Blackboard but thought I might get a quicker answer here.
