Virtual File System

OpenCms comes with its own filesystem. Most data like the dynamic pages of the OpenCms Workplace as well as websites and website templates are stored in a special filesystem, the so-called Virtual File System (or VFS in short).

The VFS is completely stored in the database. It has its own set of access functions, an own, operating-system independent permission model and it knows its own set of resource types. New custom resource types can be added without modifying the core routines of opencms.

The Virtual file system cannot be normally accessed on the operating system level. There are OpenCms extensions for making it available, e.g. through an FTP service. From version 7 on, OpenCms will support WebDAV out of the box.
