Part 2: ISO & IMG Files: What Are the Differences?

ISO (International Organization for Standardization) and IMG (Disk Image) files are commonly used for disk image storage, but they have some key differences:

  • ISO (International Organization for Standardization): ISO files are a standardized format commonly used for creating and storing CD, DVD, or Blu-ray disc images. They are widely supported and compatible with various software and operating systems. ISO files often have the ".iso" file extension.

  • IMG (Disk Image): IMG files are a more generic term for disk image files that can represent various formats, including ISO. While ISO is a specific disk image format adhering to certain standards, IMG files can encompass a wider range of disk image types. IMG files may have different file extensions depending on their origin and purpose.

It's important to note that some software and operating systems treat IMG files as equivalent to ISO files. This means that IMG files, especially those containing standard CD or DVD images, can often be used just like ISO files without any issues. However, the specific behavior may depend on the software or system you are using.
