>>Yes but the reasoin it is still a,.limt on VFP table sis the lock offset that VFP uses which is a 32 byte integer from the actual location so if a vfp table grew beyond the 2 gb barrier then the lock on record one could be hitting the location of another record in the table. When the tables are kept below 2 gb then the locking offset can never hit another record in the table becuase the table cannot grow to size big enough to allow that.

Hilamr,

That is correct I think. I don't how the memo file is handled if it is, because the memo contents can be scattered all over the file and is not necessarily in one place.
