The icons for Powerpoint files are display differently when viewed from different layouts.
When Small Icons are selected, the icons for .ppsx, .ppsm and .pptx types are all different.
This is normal but when Medium or Large Icons are selected, the icons for the aforementioned file types do not match those of the smaller size. However, files with .pps extension however displays the same in all size settings.
Example: Powerpoint Icons
Is there a way to have the icons display uniformly across view layouts?
