>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.

How does this affect the memo file? I assume the record lock needs to be placed only once for each record (that is, for the DBF).
