+-- The files table contains all files announced by any device. Files present

+-- version of each file is considered the "global" version - the latest one,
+-- that all other devices strive to replicate. This instance gets the Global
+-- flag bit set. There may be other identical instances of this file
+-- announced by other devices, but only one onstance gets the Global flag;

+-- the LocalDeviceID instance of the file is the one that has the Global
+-- bit.

+-- If the current device does not have that version of the file it gets the
