The Audio files are saved automatically in the same folder as the *.ONE
file to which they are associated. The notes pages and their associated
audio files should be treated as a single entity. If you separately
organize the audio files outside of the page structure, you will lose the
bookmarks that ON has inserted.
There are some caveats associated with moving notes files that have audio
attached. They were summarized in another thread on this newsgroup.
Look for a thread here entitled "How can I move (cut and paste) notes
with audio?" from about 5/20.
Hope this helps!
