Mixed local and network access to tables

This subject seems to be a big problem (this newsgroup has a lot of
questions related to this).

The problem:
you want access to a database file stored on a local drive (let's say
c:\x\sample.db'). The c:\x folder is shared properly, but the others
cannot see the changes made in this file and vica versa.

The solution:
set the LOCAL SHARE setting (in BDECFG/System tab) to true.
