Block All Programs from Internet Connections Under Given Folder

I happen to find a very useful video: youtube-video-block-program

Situation:

sometimes, we do not want specific program to connect internet at any circumstances, and we know this type of blockage can be done by setting the firewall in/out bound rules.

however, it is inconvenient and time consuming if we want to add many different executors.

especially, when we don't have a sense that for which executor that we want to block.

therefore, the simple solution is to shutdown the entire folder from internet accessing.

then we can predefine a rule, for example, any file with an extension exe, will be added to the blacklist.

so, here comes to the bat scripts.

This is my script: block-entire-folder-from-internet-connection
