Richard, I don't know how your response got to another thread, but I'm going to ask my folloup here. If I move files from one folder to another on the source, will backup not make that change on the destination? -- Kyle ------------------------------------------------------------------------ Kyle's Profile: http://forums.slimdevices.com/member.php?userid=2541 View this thread: http://forums.slimdevices.com/showthread.php?t=22486 _______________________________________________ Discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
