The file that was created - an ISO image - is a 1:1 representation of the bytes that would be burned to optical media if you managed to burn it. However, 18.4GB is too large for most optical media. (more on that in a sec). As Camaleón said, you could split the ISO file into bits using split(1) and re-assemble in the future using cat(1), but the bits themselves would not be useful until re-combined, so you almost certainly do not want to do that. Instead, first make sure you know what target size you need to hit. What media are you writing to? You can fit approx 600-800M onto a CD-ROM, ~4.5G onto a single layer DVD and 9G onto a dual-layer, 25G for single layer Blu Ray and 50G for dual-layer Blu Ray. (more at http://en.wikipedia.org/wiki/DVD_recordable#Capacities and http://en.wikipedia.org/wiki/Blu-ray_Disc_recordable) So you could conceivably fit 18.4G of data onto a single or dual layer Blu Ray disc, if you have the equipment to read and write them. However, you would most likely want to delete your ISO file and create a new one for the Blu Ray, since you need to use a different filesystem layout (UDF instead of ISO) for blu-rays. (I'm not sure what tools to use in this case.) Assuming you don't have Blu Ray writing equipment, you would need to use multiple disc of another format. You need to divide up your files into sets which would be burned to different discs, and generate an ISO for each. datapacker (<http://packages.debian.org/datapacker>) is one tool that could help you with the dividing stage. genisoimage (which you already know) produces the images; you can then burn them using your existing tools or 'wodim' on the command line (which I find more reliable). -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
