With the file extension ISO CD / DVD / HD-DVD / BluRay images (images) are marked .. These contain the complete image (data and structure) of a CD / DVD / HD-DVD / BluRay and can also back to an optical disk be burned. ISO is a standardized format derived from the ISO 9660 standard for CD file systems. However, the ISO file may also contain data in an extended form of this standard, such as e.g. UDF included.
Several types of programs can handle these files. Programs that provide virtual disks (such as Daemon Tools) and burn programs that write the data to an optical disk. Also, many programs can open and unpack standard ISO files. Special applications (eg ISO Buster) that can manipulate the contents of an ISO file are also available.
In Windows 7, a program called isoburn.exe is included that can burn ISO files.
