+<p>
+A virtual filesystem (VFS) is an <a href="../c3ref/vfs.html">sqlite3_vfs</a> object
+that SQLite uses to interact
+with the underlying operating system.  Most SQLite builds come with a
+single default VFS that is appropriate for the host computer.
+New VFSes can be registered and existing VFSes can be unregistered.
+The following interfaces are provided.</p>
+
+<p>The sqlite3_vfs_find() interface returns a pointer to a VFS given its name.
+Names are case sensitive.
+Names are zero-terminated UTF-8 strings.
+If there is no match, a NULL pointer is returned.
+If zVfsName is NULL then the default VFS is returned.</p>
+
+<p>New VFSes are registered with sqlite3_vfs_register().
+Each new VFS becomes the default VFS if the makeDflt flag is set.
+The same VFS can be registered multiple times without injury.
+To make an existing VFS into the default VFS, register it again
+with the makeDflt flag set.  If two different VFSes with the
+same name are registered, the behavior is undefined.  If a
+VFS is registered with a name that is NULL or an empty string,
+then the behavior is undefined.</p>
+
+<p>Unregister a VFS with the sqlite3_vfs_unregister() interface.
+If the default VFS is unregistered, another VFS is chosen as
+the default.  The choice for the new VFS is arbitrary.
