To compensate for slow, early CD-ROM speeds, various types of data in SI files are often interleaved so they can be read as one continuous stream. For example, a chunk of music data may be followed by a chunk of animation data or a bitmapped graphic. This helps reduce the amount of seeking around the disc for assets, but needs to be taken account when extracting data from an SI file since one file stream may be separated into several chunks with chunks of other data types between them. | To compensate for slow, early CD-ROM speeds, various types of data in SI files are often interleaved so they can be read as one continuous stream.
