How do I set permissions on an individual file within a document library in SharePoint?
Go to your document library
Click to the left of the File you want to set permissions on so that the tick appears:
Click on the information icon on the right hand end of the grey bar at the top of the document library:
The information bar will appear on the right of the page:
Click on 'Sharing' in the information bar
The list of users that can currently view the folder will be shown
Scroll to the bottom of the list and click Advanced at the bottom to view the more traditional (and helpful) permissions page.
The file will be inheriting permissions from its parent – this needs to be changed. Click 'Stop Inheriting Permissions' at the top left.
A warning message will appear:
Click OK to proceed.
Grant access to individual users or groups to this folder. Click 'Grant Permissions' in the top menu.
The Sharing pop-up will be displayed.
Type the user's name or userid (or group name) in the 'Enter names or email addresses' box and pick the right name from the list that appears.
Click 'SHOW OPTIONS'
Untick 'Send an email invitation'
Select the appropriate permission level in the 'Select a permission level' drop down menu, e.g. Contribute.
Click Share to finish.
Refresh the page to see your additional users/groups showing in the permission list.
You can also remove permissions for users/groups that have been inherited from the top level by ticking the box to the left of the user/group then clicking the 'Remove User Permissions' button at the top.
