I'm not sure if this is possible or not? If not I just want it to be known I could really do with it..

I've been away from my school for the last 5 weeks out of my control, I've come back this week to find some .exe files on our Fronter.

I booted one up, and discovered to my horror they're programs we're licenced for, but not to distribute to the children.

It's not the first time this has happened, but I'm just wondering if Fronter has an option to disable .exe file extensions being uploaded?

Not to my knowledge.
