## Freezing DLL Projects

Use the Project > Freeze Exports menu command to freeze a entire project, normally a DLL, to ensure backward compatibility of a new release. The result is a .def file that can be imported into other projects. You cannot freeze a single file of the project, only the entire project. Also, once a project is frozen, only new exports can be added.

NOTE A .def file must be included in the project target to export a project. The IDE will not create one if it is missing.

#### Freezing an Active Project

1. Select the Project > Freeze Exports menu item or Right-click and select Freeze Exports from the context menu

The appropriate abld command is called in the background and a .def file is generated that can be imported into other projects.
