Hi.
The Import Folders function works well for what it's designed for. And you can't do that on OneNote without third-party tools.
That said, a one-way synchronization (i.e., folder to notebook) in Evernote has benefits beyond backup. I import folders on multiple PCs so I can access them centrally no matter what device I am using. Some of these source PCs do not allow remote access. I could set up cloud drives, but they are simply to slow and clunky to use when working with large multimedia files, for example, or even a simple Word document.
Tried using OneDrive and Word 365. Go
