📁 Directory Structure

Understanding the physical structure of ABCD folders is vital for system administration, backup, and troubleshooting.

Root Overview​

A standard ABCD installation is divided into three main pillars:

ABCD_ROOT/
├── cgi-bin/       # The "Engine" (Binaries and Scripts)
├── htdocs/        # The "Application" (Web Interface: PHP, JS, CSS)
└── bases/         # The "Data" (Databases, Configuration, Formats)

tip

Always separate your Data (bases) from the Application (htdocs). This makes upgrading the software easier without risking your library data.

1. The cgi-bin Folder​

Contains the executable files that process the ISIS databases.

  • **wxis.exe / wxis**: The web-isis bridge software.
  • mx: (Optional) Administration utility for command line.

2. The htdocs Folder​

Contains the web application code. Do not modify files here unless you are a developer contributing to the core code.

  • central/: The main management interface (Cataloging, Circulation, etc).
  • opac/: The public access catalog interface.
  • assets/: Images, CSS, and Javascript libraries.

3. The bases Folder (Your Data)​

This is the most important folder for backups. It contains all bibliographic records and local configurations.

  • par/: Parameter files defining database locations.
  • lang/: Translation messages (if customized).
  • [database_name]/: Each database (e.g., books, users) has its own folder here containing:
  • data/: The Master File (.mst) and Inverted File (.xrf, .cnt).
  • def/: Field Definition Tables (.fdt) and input worksheets (.fmt).
  • pfts/: Print Format Tables (.pft).
