censhare uses a Virtual File System (VFS) to access assets and their storage items.
Overview
The VFS creates a storage hierarchy and access paths to assets and storage items from the censhare Server on a local HDD. This article gives a rough overview of the technology behind that. Each modern OS is divided into two fundamental layers. The "user space" and the "kernel space". Within the user space the normal applications, like InDesign, Safari, the Finder as well as the censhare Client are running.
Among other things, the kernel space provides access to mass storage devices, the network, etc. There are several so-called kernel extensions, like HFS, NTFS or WebDAV which do the "hard work" of representing the bits and bytes of a mass storage as real usable data (files and folders). In other words, the kernel space provides an abstract interface to access data, wherever they are and however they are stored. Mounted volumes on your computer are using exactly this abstract interface to display your files and folders within e.g. Finder.
The censhare VFS uses this technology, too. It is divided into a kernel extension and a userspace API.
The KEXT is loaded into the kernel and is available all the time your computer is running. It is the heart of the virtual filesystem and implements several functions that are triggered by the kernel and/or applications from userspace. These are functions like "mount", "unmount", "give me the content of directory w", "does file x exist", "open file y", "read n bytes of file z starting at position m", and so on. For example, Finder uses these functions to crawl through the mounted filesystem and to present its content to the user.
The userspace API provides on the one hand several methods to control the virtual filesystem and to check its health (mount & unmount it, configure it, is it mounted, ...). On the other hand, it mirrors the most significant requests to the KEXT into the application, which uses the API - the censhare Client.
In other words, the censhare Client defines the content of the filesystem and how it is accessed. That's the reason why the mounted device doesn't show any kind of information if you try to access it with the Finder but if you know the complete path, you could access the content of any asset you're authorized to.
