>That's not entirely true. You can access and update fox2x table in VFP w/o converting them. However they'll be converted to VFP if you perform on them any command that requires exclusive use of table, like INDEX, PACK and so on.

Nope, the only action that you can perform that'll deny Fox 2.x from opening a table that's been accessed via VFP is to add the table to a database. In fact, if a table has become corrupted in 2.x and cannot be opened with that version, opening and packing it in VFP often corrects the problem (usually connected to a bad record count in the header).
