Hi Peter,
When using Zetadocs Express, documents are always archived to SharePoint using DATE subfolders and this cannot be customised. When using Zetadocs Delivery and/or Capture editions, you can customise the subfolders that are used when archiving documents to SharePoint.
See here for info on Zetadocs for NAV Delivery and capture editions available.
Please contact sales@equisys.com for further info.
Kind regards,
