Mac user .
I have started writing my photos to 4.7G DVD's rather than 700MB discs.
I find that when I put items in 'burn' folder, they seem to be under the 4.7G limit - but when I try and burn a DVD it says ? MB overflow - remove some files & try again . I do that & it writes fine.
Are there any programs that will split a large file into 4.7G chunks ready for writing?
