Block files by extension

[Bad boy Warrior]

Im trying to block users from downloading all files except ones i specify. I know i can block downloading all files by using the group policy option "Disable Save this program to disk option" but that does all files.

Is there a way i can specify which files can/cant be downloaded? I know you can do this with ISA but we dont use it so another option would be real good.

cheers

If my memory is right, outlook let's you customize what file types you can download, but i don't remember a windows setting that does the same thing.
