+ * Class to provide access to ownCloud filesystem via a "view", and methods for
+ * working with files within that view (e.g. read, write, delete, etc.). Each
+ * view is restricted to a set of directories via a virtual root. The default view
+ * uses the currently logged in user's data directory as root (parts of
+ * OC_Filesystem are merely a wrapper for OC_FilesystemView).
+ *
+ * Apps that need to access files outside of the user data folders (to modify files
+ * belonging to a user other than the one currently logged in, for example) should
+ * use this class directly rather than using OC_Filesystem, or making use of PHP's
+ * built-in file manipulation functions. This will ensure all hooks and proxies
+ * are triggered correctly.
+ *
+ * Filesystem functions are not called directly; they are passed to the correct
+ * \OC\Files\Storage\Storage object
