On this page, you can learn about what ISO files are, how to create ISO files, how to mount ISO files, how to burn ISO files, and how to extract ISO files:

First, we start with the definition of an ISO file. The subsequent sections will elaborate on what an ISO file is, including its characteristics.

What is an ISO file? An ISO file is a disc image file format commonly used to store an exact replica of a CD, DVD, or Blu-ray disc. The name comes from the ISO 9660 file system standard established by the International Organization for Standardization (ISO). An ISO file contains all the data found on a disc, including files, folder structures, and boot information, allowing users to create backups of discs or mount and access their contents virtually without the physical disc. Users can burn ISO files to a disc using specific software or mount them as a virtual drive within an operating system to browse and utilize the contents. ISO files are widely employed for distributing software, creating system recovery disks, and archiving large datasets.

An ISO file, or an optical disc image, is an exact replica of an entire optical disc, such as a CD, DVD, or Blu-ray, archived into a single file. This file, referred to as an ISO image, is a miniature version of large datasets. Many people use ISO files to back up their discs or more practically store data. Now that we've defined what it is, let's delve into more details about ISO files.

    • File Format: ISO 9660, UDF (ISO/IEC 13346) file system
    • Supported Systems: Windows, macOS, Linux
    • Features:
    • COPY/BACKUP the original disc and store it: In the absence of a physical disc, you can use an ISO file to transfer a game (for example) from an old CD to your laptop.
    • Ideal container for large programs or operating systems: By uploading large programs or operating systems to an ISO file, they can be easily downloaded, mounted, or burned to a disc.
    • Features:
    • Up to 8 subdirectories (this limit can be increased with a tool)
    • 32-character maximum filenames
    • Typically 650 MB per file, though actual size can vary depending on CD or DVD capacity

Now that you're more familiar with ISO files, let's learn how to use them.
