I'm trying to burn three data files, each 1,566,790,656 bytes, to DVD+R. The three files, in total, amount to 4,700,371,968 bytes, which is 336 bytes short of the 4,700,372,992 byte limit allowed on single-sided/layer DVD+R media. In the compilation window, Nero lists these files as being 1,530,069 kilobytes each (which, when converted, add up to a total of 4,700,371,968 bytes - the same figure as before).
When I try to actually burn these files, as a finalized, non-multisession disc, Nero gives the following error message:
*** There is not enough space to burn this compilation onto this disc.
*** Please insert another disc that provides more space...
*** Data to be written: 4,483 MB (4,700,766,208 bytes)
*** Space available on disc: 4,482 MB (4,700,372,992 bytes)
Can someone please explain why Nero would first list the compilation as being 4,700, 371,968 bytes and then later change that figure to 4,700,766,208 bytes?
