What a .one file is
A .one file is one section of a OneNote notebook. Modern OneNote keeps notebooks in OneDrive and syncs them, so a loose .one file is usually an old local notebook or a backup. OneNote on Windows and Mac can open it via File > Open Notebook — double-clicking often does nothing useful — and OneNote for the web only reads notebooks that live in OneDrive.
Converting it
A .one file is commonly converted to .pdf, .docx or .onepkg. It is a binary format, so a text editor will show unreadable characters rather than its contents.
