m = lines1aim (how many lines before it prints each time)
i = lines1 (what line it starts at)
x = lines2aim (how many times it prints updates per file, so lines1aim * lines2aim = total lines printed)
h = lines2 (what line it starts at 2)
y = maxfiles (how many lines it makes)
z = startatfile (the lines have numbers at the end, so this is what number it starts at, maxfiles - startatfile = amount of files made)

printing slows down the program so lines1aim should be larger than lines2aim
