I ran "Microsoft Support and Recovery Assistant" on my OneDrive. It reported OneDrive may start to decline when you store more than 300,000 files in a single OneDrive business account. To work around this limit, ensure files are stored in multiple libraries." I have more than 900,000 files. So, I created 5 SharePoint Libraries. Moving the data from OneDrive into the new SharePoint Libraries took a long time. In order to see the new libraries, I clicked the link 'Add shortcut to OneDrive' on the SharePoint web interface. If I did not do that I could not see the file in File Explorer. Now when I run "Microsoft Support and Recovery Assistant" on my OneDrive it still says I have more than 300,000 files, presumably because the OneDrive folder sees more than 900,000 files. But these are from shortcuts to 5 Libraries. How can I fix the situation, so the 5 SharePoint Sites are visible in File Explorer without exceeding the 300,000 limit?
According to video here https://support.microsoft.com/en-us/office/sync-sharepoint-files-and-folders-87a96948-4dd7-43e4-aca1-53f3e18bea9b you can add SharePoint to Windows File Explorer not using OneDrive. I can only get files locally on my hard drive by pressing the Sync Button in the SharePoint site AND pressing 'Add shortcut to OneDrive'. I have also managed get a SharePoint library available in file explorer as a network drive but then the files are not stored locally.
There are suggestions it can be made to work using the SharePoint classic view. But I have found classic view illusive. The option only appears on sites that I do not own?
How do I make multiple libraries available in file explorer but not using OneDrive or as a network drive?
