Understanding CISO and ISO file formats
The CISO file format, also known as Compact ISO, is a compressed version of the ISO file format. It is primarily used to reduce the size of ISO files, which are disk image files that contain the complete contents of a CD, DVD, or Blu-ray disc. CISO files are often used in gaming consoles to save storage space while maintaining the functionality of the original ISO file.
On the other hand, an ISO file is a standard disk image format that contains all the data from a disc. It is widely used for distributing large software packages, games, and operating systems. ISO files are versatile and can be mounted as virtual drives or burned onto physical discs.
Why convert CISO to ISO?
