disk image and iso

Copying the files off a CD is not considered making a disc image. Making an ISO of a CD is. It’s a faster process in general also, and then when you want to move the file, instead of moving hundreds files, you move 1.

An ISO image is an archive file (also known as a disc 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 a UDF file system since UDF is backward-compatible with ISO 9660.

An ISO image includes all the data of files contained on the archived CD/DVD, or any other disc format. They are stored in an uncompressed format. In addition to data of the files it also contains all the file system metadata, including boot code, structures, and attributes. ISO images do not support multi-track, thus they cannot be used for audio CDs, VCD, and hybrid audio CDs, which are usually ripped as audio files. However, for disks that contain a single track of data followed by tracks of audio, such as video game disks, the first track can be burned as an ISO, and the rest as audio files.
