I was running some timing tests to optimize the speed of SQL Backup. When I finished I was going back to 'cleanup' the files. The actual backups that were created could be deleted, but I have about 10 files that are 1KB in size that were created with the NoWrite option. When I go to delete those files I get a window that says, "Cannot delete DataWarehouse_db_20071023_133309.sqb: It is being used by another person of program. Close any programs that might be using the file and try again."
