When you make any changes to your current project, an asterisk appears beside the name of the project in the title bar, as well as beside the project Work Units that have changed in the Project Explorer. It is a good idea to save your project on a regular basis.
In some cases, you may not be able to save parts of your project if one or more Work Units that you have modified are read-only. Before you begin working on a Work Unit, verify that you can save any changes that you might make. When using a source control system to manage your project files, keep in mind that you will need to check out your project files in order to save them. For more information on saving project files that are managed by a source control system, refer to Saving Your Project When Using Perforce.
Any fixes of project inconsistency errors listed in the Project Load Log dialog box will not be saved until you save the project. For more information about these errors, refer to Resolving Project Inconsistencies.
To save a project:
Do one of the following:
From the Wwise menu bar, click Project > Save.
Press Ctrl + S.
The changes that you have made to your project are saved, and you are returned to the project.
