Help with Binary: "Splitting up" and "Putting Together" Numbers

[ThunkGames]

I am working on speeding up the loading in my sandbox game by reading and writing to and from binary files instead of text files.

I can use this code to "break down" an integer into bytes as to write them into binary files:

var b1 = int >> 24 & 255;
var b2 = int >> 16 & 255;
var b3 = int >> 8 & 255;
var b4 = int & 255;

But I don't know how to "put together" these 4 values after I read them.

b1<<24|b2<<16|b3<<8|b4

use the buffer write and buffer read system instead of binary files

As icuurd said. I tried using text files for a paint editor I made some time ago. It saved the individual colours on the image 1 by 1. And these were million digit sized numbers (16,546,234). Text files worked but were incredibly slow. Using buffers instead increased the speed dramatically.

Thank you very much. Load speeds for my game have been tripled. I had already been using buffers to store block data "in game", but needed to store unloaded chunks of data on the user's disk.
