Hi,
My understanding is that SharePoint provide "FileOperationSettings" property to disable Shredded Storage but this property is not working in SharePoint 2013 RTM release.
Only the way they provide is modify the FileWriteChunkSize property and set the chunk size is 2 GB for bypassing the shredded storage.
Is there any another way to disable the Shredded Storage in SharePoint 2013 and store the document in database same as SharePoint 2010 does?
