What is ISO format?

ISO (ISO Disk Image)

The ISO file format, often referred to simply as an ISO, is a disk image of an optical disc. It captures the complete contents of a CD, DVD, or Blu-ray in a single file, including the file system and metadata. This format is particularly useful for distributing software, operating systems, and large multimedia files, as it allows for a straightforward method of duplication and sharing of data.

ISO files are typically used to create exact copies of discs, making them ideal for backup and archiving purposes. Users can mount ISO files as virtual drives, enabling easy access to the contents without needing to burn them to a physical disc. This functionality is particularly handy for users who want to run software or access files without the hassle of dealing with physical media.

Moreover, the ISO format supports various file systems, including ISO 9660, UDF (Universal Disk Format), and others, which enhances its compatibility with different operating systems and devices. When an ISO file is created, it retains the original structure of the files and folders, preserving the integrity of the data.

ISO files are commonly used in the software distribution industry, particularly for operating systems like Linux and Windows, allowing users to download and install software easily. They are also used in gaming, where game developers distribute their titles in ISO format for easier installation and setup.

Furthermore, ISO files can be easily converted to other formats, providing versatility in how they are utilized. The ability to compress these files also makes them more manageable for storage and transfer over the internet.
