This key is optional and can take a value between zero and 4096 (the default). It is the number of kilobytes in each segment file. The segment size cannot be changed once Equinox has created the first additional segment file (for example TBL21.R01), except via export and import. If the wrong segment size is used, undefined results will occur.

BLB files now support multiple segments in the same way as record and index files and the total data can reach a maximum size of 32 times the SegmentSize setting.

RCD and INX files can reach 256 times the segment size, or two billion records, whichever is the smaller. When Equinox reaches the segment size, it creates a new file automatically and continues to store data in the new file. For a base table TBL21.RCD, the first segment file is called TBL21.R01 and so on in hexadecimal. However, to avoid conflicts with the base filename, the hexadecimal numbering is 0 1 2 3 4 5 6 7 8 9 U V W X Y Z, and so the last file is called TBL21.RZZ.
