The Update Reports command will update all tables you have created.  Sometimes, you want to delete a table and not have it 'come back' when you run the Update Reports command.

The software stores a list of created tables in the Data folder (look in the -Data folder in the AdvRoads-10 folder) called AutocadTables.txt.

Inside that file is a list of the tables created. When the update button is run, it looks in this list and then finds/creates the tables listed. If you delete the file or delete the line entries in the list, you will stop this updating.
