DVD-R: writing data files to dvd, what is the size limit per individual file? 2GB?
Posted on 2004-09-30
Is there a 2GB per file limit of a 4.7GB DVD-R? If so where does it come from? I'm trying to write a backup image file that is 3.9GB to DVD as data, and I get wierd errors using Roxio that don't make sense. (buffer underrun). The support FAQ for Acronis says that to write using this two-step method you need to split the image into 2GB files when you create it, if you plan to burn it to dvd. This seems likely to be my problem, but now I'm curious about the file size limit. NTFS on a hard drive has no such limit, but maybe the DVD is a different animal. Is the file system on dvd related to FAT or something? That's what it reminds me of.
