Hello Team,
Greetings!! 
I am relatively new to salesforce. I am using a Developer edition.  I am trying to set the Permissions for Reports and Dashboards but I am  not able to locate the “Folder Sharing ” option .I searched through Quick Find box , looked through various options but still I am not able to find it.
Searched via Setup|Customize|reports and Dashboards & found only the below 4 options
Reports and Dashboards Settings
Historical Trending
Report Notifications
Access Policies
Tried to check the profile permissions but did not find any option to check regarding the sharing options

Could any one please suggest ?
