Powerpoint compress low quality 2013

[mm3]

Hello!!

 

just noticed a lot of the pupils are hitting their quota limit on the home dir; found lots of large PowerPoints due to the size of embedded videos/audio/images.

 

I've started to compress them to low quality this is saving huge space (a ppt was 100mb after compress they are now 10mb)

 

I'm wondering is there a powershell or script to do this without me having to go through an open these files one at a time?
