Mr Pontello, scale your dbf files op with the datapump utility which comes with Delphi. Maybe you have to rearrange some of the properties by yourself, but at least the data, keys and indexes will be transported automatically.
But before you do this look into Interbase domains. These are very powerful when you need a certain type of fields in more than one table. Unfortunately altering a domain afterwards, results in dropping (temporary) the related fields.
