img and iso files

[ZollyMonsta]

Hi All,

I'm using an authoring programme for dvd and I have to export to hard disk as it will not write directly to my DVD writer (NEC 1300A).

The image files it creates are .img
My DVD writing software reads .iso files

Are these file formats the same? I changed it from .img to .iso last night and successfully burned it using my dvd writing software, but to a DVD-RW.

Just interested to know if there is any major difference, or if it's just manufacturer preference as to what they name the extension.

I don't think they are the same, but I know that in most cases you could try to rename... hm... I'll try to come up with something

Found:

Disk Image Formats
ISO - ISO-9660/Joliet CD Images
ISO is a commonly used file extension for disk images that use the ISO 9660 standard. These images use the ISO 9660 file system; and can also use Joliet or RockRidge file system extensions. ISO files always contain images of CDs, not floppies or hard drives. ISO images are commonly used to store and transfer contents of entire CDs. Most CD recording programs can burn ISO images to recordable CDs. Some of these programs use ISO as their native disk image format.

IMA/IMG - Generic Disk Images
A generic disk image (also referred to as a plain or raw image) is simply a binary copy of a source drive. There are no format specifications for this type of disk image, because it simply contains raw data with no extra information. Generic image files are not drive-dependent. They can contain images of any kind of drive—a CD, a hard drive, a floppy, removable drive or any other disk device. Usually IMA/IMG files contain images of floppy disks and hard drives. Most CD recording programs recognize IMA and IMG extensions and can use these images as boot images.

Hope that was it...

You could use UltraISO to convert this to the filetype you need...or, better yet, just use DVD Decrypter to burn the file, no need for converting. DVD Decrypter burns so many image formats and its free, it doesn't get much better than that for freeware IMO.
