Last change on this file since 1354 was 1354, checked in by Gregg Young, 17 years ago

Added driveflags to over ride write verify for USB removable drives that fail when it is on (Ticket 323); A flag to prevent directory name from being broadcast to drives in the tree cnr prior to a recursive scan of the drive (causes dbl directory names Ticket 321) Add option for multithreaded recursive scan of user selected drives at startup (Ticket 322).
