Why do results of recovery contain less data than the original OneNote file?
This is normal. The damaged parts of your OneNote file will convert to zero size on output. The other common reason of file size decrease is when some of features of the original file are not supported and therefore absent from the recovered file.
Demo-recovered file is smaller because it mostly consists of demo placeholders than actual data.
