What structure should it have for this?
look at FOXDBE (DATA-Komponente)
Tabellen Dateigröße Limitiert auf 2^31 Bytes (2 Gigabyte)
Max. Anzahl Felder 2038 *)
Max. Anzahl Datensätze (2^31 - Header() - 1) / RecSize()
more Field -> less Records to reach 2 GB.

the Problem is DBFDBE_LOCKOFFSET which default is 1000000000 which is Cl*pper compatible
you can change to max. 2.4GB using 8FFFFFFF (not 0x80000000 )

but this is not compatible any more :!:

---

under harbour you can use extend DBF up to 2^41 -> 2TB (Terabyte) max file size
