• read numbers from the file into an array
• sort numbers
• write numbers back to the file

If there are too many numbers to fit in computer memory:

* Divide into portions that do fit
* Sort each portion separately
* Save sorted results to individual files
* Merge the results by reading these sorted files, always picking the smallest number available in any file.

This is called a merge sort
