## Show Warnings/Prompts for

### Saving projects

Every time you save a standard Audacity project or a compressed copy of a project, Audacity will warn that this command is only for an Audacity project and that you must use an export command to produce an audio file that you can open in other applications. Once you understand this, you can turn off both these warnings from within either warning dialog.

### Saving empty project

Audacity will warn when you try to save (left-hand image) or close (right-hand image) a project that previously contained tracks but is now empty. This warning can only be turned off in Preferences (not by a checkbox in the warning) because of the risk of accidental data loss if the warning is disabled.

### When mixing down to mono during export

Audacity will warn when a mono audio file will be created as the result of an export operation that involves mixing two tracks or more.

### When mixing down to stereo during export

Audacity will warn when a stereo audio file will be created as the result of an export operation that involves mixing two tracks or more. If you normally want to export to stereo audio files you can turn this warning off.

### When mixing with Custom FFmpeg export

Audacity will warn that your export will be to a single file according to your encoder settings.

### Exporting an audio file with no extension

Audacity will warn when you try to export an audio file with no extension when exporting using {external program).

## Low disk space at application start up

This warning message can no longer be turned off in Warnings preferences or in the warning dialog itself as it is deemed a critical warning.

Audacity will warn on start up or when using File > New to create a new project if you have 100 MB or less space in the temporary folder for recording or editing.

100MB is approximately 5 minutes of stereo audio or 10 minutes of mono audio at default settings.
