Using a project to save macros has many advantages, such as easier management of multiple files and restoration of the previous environment. If you save code in a VB or VBA project, you can open the code in the respective IDE only. If you save code in modules, you can import the module into either VB or VBA projects.

You save macros with the following file extensions.

Extension	Description
.dvb	AutoCAD Map project
.bas	Visual Basic
.cls	Class module
