What is an ISO image file? The ISO image file is a duplicate copy of a complete CD-ROM disk saved in ISO-9660 format. ISO image files are widely used for storing CD content and quickly transferring it through the Internet. ISO is a common CD image format for DOS, Windows (Joliet ISO extension), Linux (RockRidge ISO extension), and other operating systems. An 'iso' file is just a disk image.
The ISO image is an archive file (also known as a disk image) of an optical disc in a format defined by the International Organization for Standardization (ISO). This format is supported by many software vendors. ISO image files typically have a file extension of .iso. The name ISO is taken from the ISO 9660 file system used with CD-ROM media, but an ISO image can also contain UDF file system because UDF is backward-compatible with ISO 9660.

What is cso? A file with the CSO file extension is a CISO Compressed ISO Image file. These files are mainly used by the PSP2 system for games. .cso is short for Compressed ISO Image, which is a compression method for the ISO image format. It is used to compress dumped PlayStation Portable UMD games, and is an alternative to the .DAX compression method. It is also sometimes called 'CISO'.
CSO provides nine levels of compression. While the highest levels of compression can introduce slowdown and lengthy load-times in software which relies heavily on disc streaming, even the lower levels are capable of substantial compression. This is partially due to the data layout of a UMD, though more frequently due to the use of Dummy Files as both an anti-piracy tool and a means to more optimally lay the data out physically on the disc.
ISO files are a common disk image distribution format. We'll look at the best ways to converter iso files to cso.
