How Would I Change GetFullName to a directory?

ok, so I have filtering enabled and Im trying to make a destroy part script with a pickaxe. Heres the localScript,

local swing = script.Parent.Swing
local db = 5
oof = false
event = game:GetService("ReplicatedStorage").BlockBreak
script.Parent.Activated:Connect(function()
	if not oof then
		oof = true
		local plr = game.Players.LocalPlayer
		local Char = workspace:WaitForChild(plr.Name)
		print(Char)
		if Char ~= nil then
			local animTrack = Char.Humanoid:LoadAnimation(swing)
			animTrack:Play()
			db = 6
			wait(0.8)
			db = 5
		end
		wait(5)
		oof = false	
	end

end)
script.Parent.Handle.Touched:Connect(function(hit)
	if db == 6 then
		local naa = hit.Parent:FindFirstChild("HitTag")
		if naa ~= nil then
			event:FireServer(naa:GetFullName(),hit.Parent:GetFullName())
		end
	end
end)

And ServerScript:

event =  game:GetService("ReplicatedStorage").BlockBreak
event.OnServerEvent:Connect(function(plr,bVal,name)
	loc = name
	loc2 = bVal
	
	print("Recieved Order from "..plr.Name.." to break ".. loc)
	if loc ~=nil then
		wait(1)
		
		name.Parent = nil
		print("Logged")
		loc.Parent:Destroy()
	end
end)

The problem is that name is a string, how would I turn it into a directory so I can destroy the part?

You should do this on the server so that the client does not fire the remotes you have through exploits. I wrote a simple script that does this. Please put it in ServerScriptService.

local Players = game:GetService("Players");
local Tool = script.Tool -- Tool location
local PlayerTools = {};


function giveTool (Player)
	Player:WaitForChild("Backpack");
	local newTool = Tool:Clone();
	newTool.Parent = Player.Backpack;

	local playerTool = PlayerTools[Player.UserId]
	if playerTool then
		if playerTool.touchConnection then playerTool.touchConnection:disconnect(); end
		if playerTool.activatedConnection then playerTool.activatedConnection:disconnect(); end
		if playerTool.tool then playerTool.tool:Destroy() end
	end
	
	local isActivated = false;

	local touchConnection = newTool.Handle.Touched:Connect(function(hit)
		if not isActivated then return end
		if hit and hit:FindFirstChild("HitTag") then
			hit:Destroy()
		end
	end)
	
	local activatedConnection = newTool.Activated:Connect(function()
		if isActivated then return end
		isActivated = true
		wait(0.8)	
		isActivated = false
	end)
	PlayerTools[Player.UserId] = {
		tool=newTool,
		touchConnection= touchConnection,
		activatedConnection = activatedConnection
	}	

end

Players.PlayerAdded:Connect(function(Player) 
	giveTool(Player);

	Player.CharacterAdded:Connect(function(character)
		giveTool(Player)
	end)
end)
