Hello Gerard, Please refer my other message and if it were possible to do your suggestion below, the disk spanning option would also be possible, possibly ;-) g> It would be similarly possible to add a file that has grown in size at the g> end of the file and invalidate the old entry in the CD, for example in the g> extra field of the file header in the CD. g> What do you think ? g> Regards, g> Gerard. -- Regards, Alistair+
