File Menu: Save Project

Save Project Ctrl + S
Saves the current Audacity Project in uncompressed, lossless quality using the AU container format. An AUP project file is created, along with a folder with the same name as the AUP file that contains the project's audio data. For example, if you save a project as chanson.aup, a folder called chanson_data will contain the audio data files.
If you import uncompressed files such as WAV and AIFF into your project with Import / Export Preferences set to "Read uncompressed audio files directly from the original (faster)", you will create a dependency on those files remaining accessible. In this case, a Dependencies Dialog may appear when saving the project. Follow the instructions in the dialog to either "Copy All Audio..." (so removing all dependencies), or to copy in selected files or none at all. If you choose to not copy in any files, you must not move, rename or delete those files, or the folder they are in. The dialog also lets you choose future behavior when saving a project that depends on imported files.
Save Project As...
Same as "Save Project" above, but allows you to save a copy of an open project to a different name or location. This can be useful if you want to preserve a snapshot of the state of a project at a particular time, then proceed to make further changes to the project you just saved.
If you "Save Project As..." with a new name, the project window then displays the project name you just "saved as". The project window displaying the project as previously named is closed in its last saved state, but can be reopened as required.
