What Is an ISO File
An ISO file or optical disc image is an exact copy of an entire optical disc (such as a CD, DVD, or Blu-ray Disc) archived into a single file. This file, called an ISO image, is a smaller copy of a large data set. Many people use ISO files to back up their discs or to store their data more practically. After learning its definition, let's learn more features of an ISO file.
- File format: iso9660, UDF (ISO/IEC 13346) file system
- System supported: Windows, macOS, Linux
- Replicate/copy an original optical disk and store it: When no physical disks are available, you can utilize an ISO file to transfer a game, for example, from an old disk to your laptop.
- Great container for large programs or the OS: By uploading large programs or OS on an ISO file, these OS can be downloaded/mounted/burned on an optical disk effortlessly.
- Contains up to 8 subdirectories (You can increase this limit via tools)
- The maximum file name is 32 characters
