Get-Rules Block 🎦

1. Creates the Rules folder in %USERPROFILE%\Rules if not present
2. Dumps all "allowed" firewall rules into a textfile at %USERPROFILE%\Rules\FW-Rules.txt
3. Stock the rules into a variable from the file dumped (user can use custom file/path)
4. Parse each rules ending at '(?<=Action: Allow)'
5. Create a .txt of each rules at %USERPROFILE%\Rules$i.txt
6. Increment until none left

Conversion (Rules, Groups) 🔄

1. Gets the last item of the rules dumped, then starts the loop until last rule
2. Starting from rule #1, it'll extract all rule's parameters into variables
3. Then create a netsh command to re-enter it as needed, with rule's variables
4. Each set of variables creates a command which is added to a command file
5. Final textfile contains all commands ready to be applied, in the 'netsh' format.

I created this dumper to easily re-create multiple rules I needed. Be sure to note the packages or you may be missing some stuff, lemme know if anything is wrong! With the "Export Policy" option, you can't select which to export/import, (like the predefined firewall rules) you have to overwrite the whole set ❌
