Please consult the 
related entry if your conference has a 
two-tier (two-phase) peer review process (i.e., abstracts and full papers are peer reviewed).
If the 
full paper uploads are indeed 
final and not peer reviewed anymore (
camera-ready copies), please 
enable the final upload phase here:
Overview => Settings => Conference Phases and DeadlinesSet the deadline(s) accordingly: Deactivate the phase for "Submission and upload of contributions" and activate the phase for "Final upload of accepted contributions (camera-ready copies)" (please see image 1).
Furthermore, please set the 
number of file uploads for the final uploads for the corresponding submission types / conference tracks (please see image 2):
Overview => Settings => Manage Submission Types / Conference TracksWe recommend that you 
set two uploads to be required: 
1. one PDF file which can be used as reference or be published directly (e.g. in the agenda), and 
2. one WORD file (or a similar file format) that you can edit if necessary. 
Authors of accepted contributions can upload final versions for their corresponding contributions (please see image 3). 
NB: The 
 upload of final versions must be enabled  for the assigned acceptance status!
You can also set different 
 alternative deadlines for each submission type / track.
