Hello Robert, Thanks for reply which is is clear. I am writing a backup routine which 'Saves Directorys' but another program I am comparing it to 'Saves Directorys' as well as 'Recurse Directories' how would that be interpreted insofar as backups are concerned? Would it mean that if the 'Saves Directories' were checked that it would save the directories as the filesystem streams through all the files. Maybe the 'Recurse directories' saves the files all as one bunch in each directory until that directory is completed - do you think? Thanks, Al+
