Introduction to AOB Structure

ArOZ Online Beta follows a modular design in which a module is a folder placed inside the AOB root directory.

There are a few important directories and files in which the main functions of AOB system are written in. Including:

• index.php
• function_bar.php (and function_bar.js)
• /SystemAOB/functions
• /Upload Manager
• /msb
• /script
• /img

It is not recommend for anyone to modified these folders / files without knowing how the system works. If you are a module deveveloper, please read the "Introduction to AOB Module Structure" instead.

System Functions in AOB (/SystemAOB)

SystemAOB is the module that contains all the system scripts. Including a virtual file system based on linux kernal and it is possible to access external storage devices (e.g. /dev/sda1) from the script. The standard modules are as follows:

• file_system (Virtual File Explorer)

The standard functions are as follow:

• diskSpace.php (Check the space left on the main disk)

• videoStreamer.php (Video Streaming script for mp4 from external storage devices)

Multi-System Booting Interface Folder (/msb)

MSB Interface is not part of the AOB System. But due to the need of compatibility towards other web application and systems, msb folder was included in the standard structure of AOB. For more information, please go to the "Multi-System Booting Interface" section.
