I Love One Note.
The only problem I am having is during migration for Evernote (and for whatever reasons that individual notes have become fragmented), I have multiple One None files. I have successfully consolidated into a single Master OneNote file but still have these fragmented One Notes which I have to navigate through both in One Note and in the One Note Clipper. I can't tell the difference between Fragmented One Notes in One Drive and so I am afraid to delete anything to clear things up for fear of affecting my master file. Is there a way that you can establish a prime OneNote data file and either discard or ignore fragments to clean things up? It is frustrating to navigate each time.
