What is a(n) CSO file?
CSO (CISO Compressed ISO) is a file format developed for storing compressed ISO images. It is commonly used for archiving and distributing backups of optical discs, such as PlayStation Portable (PSP) UMDs, and GameCube or Wii discs. Not only does CSO reduce the size of an ISO file significantly, it also increases access speed when retrieving the data.
This file type is created by compressing the ISO image's raw data using either the zlib or LZO compression algorithms, resulting in a single CSO file which can then be used in place of an original ISO image. Its main advantages are portability and increased load speed compared to uncompressed ISOs, as well as reduced storage space while still maintaining data integrity.
