Audacity saves its data in a format that only Audacity can use. Audacity saves more information than just the audio files, and this information cannot be stored in conventional audio files like OGG, FLAC, or AIFF.
When you want to share your work, or use it in another application, you must export it. When you "export" audio, Audacity converts the Audacity-only file into a conventional audio file. Audacity does not delete the original Audacity-only file, but the exported file cannot be converted into the Audacity-only format.
