HI ChronoCross Nice idea and a litle complicated for me
the first Idea is awesome, but i can't help you .
I started to read LUA and looks easy to undertand.

the first is an error like data.arc is not a valid fa next file.
because the code first create data.arc with 0b.
but the second time you run the bat, fa next extract correctly because the program found a joining data in data.arc.
If someone have an idea to fix this or help to the first idea please go on!

let me help you in this part.
add some lines in your fa.ini code repeat and until ~=

onProgramStart(function ()
    repeat
	a = "none"
    f = command.arcname
    f =  io.open(f, "a")
    f:write()
    f =  io.open("data.arc", "r+b")
	f1 = io.open("data.part1", "rb")
	f2 = io.open("data.part2", "rb")
	f3 = io.open("data.part3", "rb")
    f4 = f1:read("*all")..f2:read("*all")..f3:read("*all")	
	t = io.output (f:write(f4))
	until f ~= assert ( io.open("data.arc", "r"))
	f:close()
end)

Now can join and extract the files correctly.
