This saves or updates the .aup file and _data folder. Saving a project lets you save unfinished work and re-open it later in Audacity exactly as it was and (with the exception of the undo history), with all edits and recorded/imported tracks preserved. As with saving any type of file, certain characters cannot be used in the name of the .aup file if they are reserved for the operating system; see our information on forbidden characters.

This could serve either as a single backup copy of the project, or as one of several incremental copies of the project in the state it had at a particular date and time.
To re-open a saved project:
