>>>The maximum size of a VFP table is 2 GB (a limitation that beats up Access' database limitation of 1 GB total MDB size). When a table is opened, the database manager in my framework compares the table against this limit and also determines if there is enough diskspace available to add an additional 100 records to the table. This allows the user to be alerted well in advance (hopefully) of any potential space issues.

No single file can exceed 2GB.
