Create as database project
The file created as a database project does not perform processing of compression or encryption. But the efficiency of edit is most superior. Moreover, only database project can perform relation of cards.
When creating a database project, you choose "Regular database" from "New" and choose the save place of the database file.

Please choose "Add new card define" from menu which right-clicks on the icon of that database and read template file(*.vvfrm) when the database file is added to this project.

The item of "Name" and "Alias name" is shown on the lower part of the file selection dialog. "Name" must mean the data used for management of the database, and you have to make it less than ten characters by half-width alphanumeric character and half-width underbar. On the other hand, "Nickname" is an alias which you use when expressing data, and there is no restriction in a character kind and you can input up to 30 characters to it.

Incidentally, the procedure of save is unnecessary because the data edited in the database project is written in real time.
