# Creating Drivers

## Driver Directory and File Structure

Sample driver directory and file structure layout:

- /application/libraries/Driver_name
  - Driver_name.php
  - drivers
    - Driver_name_subclass_1.php
    - Driver_name_subclass_2.php
    - Driver_name_subclass_3.php

Note

In order to maintain compatibility on case-sensitive file systems, the Driver_name directory must be named in the format returned by `ucfirst()`.

Note

The Driver library’s architecture is such that the subclasses don’t extend and therefore don’t inherit properties or methods of the main driver.
