I just migrated around 30 folders from Evernote. Most of these folders were created in order that the enex migration files would be < 500mb (requirement by Zoho Notebook).  I want to now clean up many of these artificial notebooks mostly by combining them into a smaller number each with more content. Or should there remain a large number of notebooks?

Are there performance and/or search considerations I need to consider or be aware of?

Thanks.
