The sizes of the archives within the distributed file vary from the traditional 3½" floppy disk (1.44 MB) or extra-high density disk (2.88 MB) to 5 MB, 15 MB (typical for CD images) or 20MB (typical for CD images of console releases), 50 MB files (typical for DVD images), and 100MB (for dual-layer DVD images). These measurements are not equivalent to traditional measurement of file size (which is 1024 KB to a MB, 1024 MB to a GB); in a typical DVD release, each RAR file is exactly 50,000,000 bytes, not 52,428,800 bytes (50 megabytes in binary prefix).
