Filesystem structure of a Horde application

This information is valid for Horde 4 and later only. See Doc/Dev/FilesystemH3 for Horde 3.

Each Horde application has a common filesystem structure. This helps organizing the several components of the application and simplifies working with unknown applications.

These are the directories available in every Horde application:
 || Directory || Content ||
 || / || Base directory with the controller scripts called by the browser ||
 || app/ || Views and controllers for MVC style apps ||
 || bin/ || Binary and other standalone CLI scripts ||
 || config/ || Configuration files ||
 || docs/ || Administrator documentation ||
 || js/ || Javascript files ||
 || lib/ || Application-specific library files ||
 || locale/ || Original and compiled translations; application help files ||
 || migration/ || Setup and migration files ||
 || templates/ || Template files ||
 || themes/ || Themes directories ||
 || themes/default/ || Base theme ||
 || themes/defaults/graphics/ || Base theme icons ||
Usually there are more directories, depending on the application:


    If there are many controller scripts for an application, they may be grouped into directories under the base directory.
    The lib/ directory has many levels of subdirectories. See Doc/Dev/Framework for details.
    The locale/ directory has a subdirectory for each locale, e.g. locale/de/ or locale/zh_TW/ if locale has multiple regions. These subdirectories contain the translated help file help.xml and the directory LC_MESSAGES/ which contains the actual, compiled translation, e.g. imp.mo and original source file, e.g. imp.po.
    The templates/ directory groups all templates for a single controller script into one subdirectory. All templates for a script called list.php are inside templates/list/ for example.
    Each theme has a subdirectory, e.g. themes/bluewhite/; if a theme provides its own icon set, the icons are inside a graphics/ subdirectory, e.g. themes/bluewhite/graphics/.
    Some applications have sub-sets of their icons grouped into subdirectories, e.g. themes/graphics/flags/.
