Key Concepts about Creating a Directory

NHANES data are saved in SAS transport files (.xpt). The SAS transport format allows the data files to be extracted on Windows-, UNIX-, or Macintosh-based systems. This tutorial focuses on Windows-based systems.

In this task, you will be creating directories on your C drive to hold your SAS files and documentation, as well as extracted SAS datasets. The structure outlined in this task is recommended as it will be used throughout the tutorial. If you decide to use a different arrangement of folders, change the path to the SAS datasets in the sample programs.
