When the notebook folder has been successfully saved outside of its Zip file, you can import the folder into OneNote. To solve this issue, double-click to open the original Zip file, and then extract (copy) the notebook folder from the Zip file to any location on your hard drive (for example, the desktop).

If OneNote rejects a notebook file that you’re trying to import, it’s likely that you’re trying to upload the original Zip file that was created when you previously downloaded the notebook. OneNote doesn’t recognize the notebook I’m trying to import To troubleshoot this issue, open the errors.txt file from the downloaded Zip file in a text editor and read its contents for more specific information. When this happens, something went wrong during the export process. In rare cases, it’s possible that a downloaded Zip file doesn’t contain any notebook folders but only shows a file called errors.txt. Whenever a notebook is downloaded successfully, it is saved as a Zip file that contains a folder with the same name as the notebook. My download contains only an “errors.txt” file, but no notebook folder If a download is interrupted because you ran out of storage, you’ll need to restart the download again after you’ve recovered enough hard drive space.

Before attempting to download large notebooks, make sure you have several gigabytes (GB) of available space on your computer’s hard drive. Over time, notebooks can significantly increase in size, especially if you use OneNote to collect embedded documents, image scans, PDFs, or video and audio clips as part of your notes.

If you’re running into any issues while exporting or importing your notebooks, try the suggestions below. Manually delete any unnecessary files from your OneDrive storage (including any failed notebook uploads) and then try importing the notebook folder again.

Tip: If the import process begins but then appears not to finish, your OneDrive account might be low on available space.
