See [SION File Defragmentation](Usage#sion-file-defragmentation). Note that you can still load the defragmented SION file into python, see [Linktest Python Reader](Linktest-Python-Reader), and it can still be used to generate reports, see [Linktest Report](Linktest-Report). After defragmentation the file can be further compressed using any non-lossy compression tools. The resultant compressed file can no longer be loaded into python and hence reports based on it cannot be generated unless the file is decompressed first.

TLDR: They are binary prefixes.
These are the prefixes for binary sizes, which use a base of 1024 ($2^10$), stipulated by the International Electrotechnical Commission (IEC) and accepted as an international Standard by the International Organization for Standardization (ISO) in Standard ISO 80000. They use the nearest multiple of 2 to the common Système International d'unités (SI), now known as metric prefixes, which have a base of 1000.
