Just to clarify; Audacity works only with projects, it does not operate directly on audio files. Audio is either recorded, Imported or Opened into a project. To get an audio file out of a project you Export the audio as an audio file. There are technical reasons why Audacity works in projects and not directly on audio files. This way of working is very common with advanced audio programs, though some programs call them "Sessions" (or something else) rather than "Projects". What Koz is saying is that often it is not actually necessary to Save the project at all. If you record/import something, do what you want to do with it, then Export the finished audio file, you may not need to Save the project.
Saving Projects can be useful if you are working with more complex projects with multiple tracks as the Project as the project keeps all of the individual tracks, envelope points, pan and volume levels, and various other things that are not available in the Exported audio. In such cases, Saving the project makes it easier to go back to the project at a later time to continue working on it.
When you Save a Project, Audacity opens a window where you can browse to the location where you want to Save the Project to. It is important that you Save to a location that you have full access to, such as in "My Documents", or a folder inside "My Documents".
