Answer : How can i block portable file

you are not making a hash rule to block game files. you are making a hash rule to ALLOW specific files like ones your company uses. EVERYTHING else will be blocked.

i have explained how to block the excel files. by blocking vba from runnning in excel. thats the only way short of stopping them access to excel completely.
