Does any one know if you need to provide photocopy of all the originals as well ? And does your partner have to be present without on the appointment day ? Any idea would be appreciated thanks

I have an appointment tomorrow for my ILR SET (M) with the new process ( by UKVCAS Customer Service provided by Sopra Steria ). I want to know if I have to take copy of all the original documents or just scanned and original
Thanks for your help in advance
