Package Physical Structure

A fully functional web application's installation package should meet the requirements laid upon its file and folder arrangement. The application's folder nested within the Application Vault (AV) root directory (…/<plesk_root_dir>/var/cgitory/) should look as follows:

The /apps folder is a real repository of application files, and the remaining folders are service ones used by AV mechanisms.

Folder name	Description
scripts	Contains shell and perl script files used when installing/reconfiguring/uninstalling applications on the domain side.
forms	Contains PHP files of two kinds – data input forms necessary to install/reconfigure/uninstall applications on a domain, and files with event handlers matching these forms.
apps	Contains TAR archive files that store files of the application itself and extracted on a domain.
uninstall	Contains the uninstall script used while removing the installation package from AV Repository. This script is optional.
docs	Contains a document displayed by Plesk Context Help system to describe a given application.
info	Contains the `info.xml` file that describes the application's properties. The file is necessary to display the application in Plesk Control Panel. Also, the /`info` folder contains an image used by default if a custom button is created.
screenshots	Contains screenshots of the application's GUI.
