Like earlier versions of SharePoint, In SharePoint 2013 you can set unique permissions for Folders and Items\Documents using the “Shared With” option. It is not that straight forward and it took me few minutes to get to the desired screen. Microsoft shouldn’t have Changed the design that much.. I mean people from my company are still getting hands-on on SharePoint 2010 UI and now this will be a huge Change.

Anyway.. here is the quick tip that you need.
Click on the “Call up” menu or “…” of folder or documents that you need the unique permissions on. Click on “…” further as shown in Fig. below and then select “Shared With”





Next click on “ADVANCED”.


Next click on “Stop Inheriting Permissions”.
