What Are ISO files, and How Do I Open Them?
Description[ edit ] There is no standard definition for ISO image files. ISO disc images are uncompressed and do not use a particular container format; they are a sector -by-sector copy of the data on an optical disc, stored inside a binary file. ISO images are expected to contain the binary image of an optical media file system usually ISO and its extensions or UDF , including the data in its files in binary format, copied exactly as they were stored on the disc. The data inside the ISO image will be structured according to the file system that was used on the optical disc from which it was created.

Description[ edit ] There is no standard definition for ISO image files. ISO disc images are uncompressed and do not use a particular container format; they are a sector -by-sector copy of the data on an optical disc, stored inside a binary file. ISO images are expected to contain the binary image of an optical media file system usually ISO and its extensions or UDF , including the data in its files in binary format, copied exactly as they were stored on the disc.
The data inside the ISO image will be structured according to the file system that was used on the optical disc from which it was created. ISO files store only the user data from each sector on an optical disc, ignoring the control headers and error correction data, and are therefore slightly smaller than a raw disc image of optical media. Since the size of the user data portion of a sector logical sector in data optical discs is 2, bytes, the size of an ISO image will be a multiple of 2, Unlike a physical optical disc, an image can be transferred over any data link or removable storage medium.
An ISO image can be opened with almost every multi-format file archiver. Native support for handling ISO images varies from operating system to operating system.
Hybrid disc formats include the ability to be read by different devices, operating systems, or hardware. In the past, one example of this use was for a disc that supported both Microsoft Windows and Macintosh installations from a single disk image by containing several file systems.
An ISO can be “mounted” with suitable driver software, i. Versions of Windows beginning with Windows 8 also have such capability. Since there is no standard defining the ISO disc image file format, the term “ISO image” is sometimes used in a broader sense to refer to any disc image file of an optical disc, independent of the format it uses.
Limitations[ edit ] A CD can have multiple tracks , which can contain computer data, audio, or video. File systems such as ISO are stored inside one of these tracks. Since ISO images are expected to contain a binary copy of the file system and its contents, there is no concept of a “track” inside an ISO image, since a track is a container for the contents of an ISO image.
This means that CDs with multiple tracks can’t be stored inside a single ISO image; at most, an ISO image will contain the data inside one of those multiple tracks, and only if it is stored inside a standard file system.
This also means that audio CDs , which are usually composed of multiple tracks, can’t be stored inside an ISO image. Furthermore, not even a single track of an audio CD can be stored as an ISO image, since audio tracks do not contain a file system inside them, but only a continuous stream of encoded audio data.
This audio is stored on sectors of bytes different than those that store a file system and it is not stored inside files; it is addressed with track numbers, index points and a CD time code that are encoded into the lead-in of each session of the CD-Audio disc. These formats store a raw disc image of the complete disc, including information from all tracks, along with a companion file describing the multiple tracks and the characteristics of each of those tracks.
This would allow an optical media burning tool to have all the information required to correctly burn the image on a new disc. This limitation is more related to the availability of software tools able to perform this task, than to problems in the format itself.
However, since , various software has existed to write raw image files to USB flash drives.
