From the Explore Repository, right-click the file or folder, and then select Edit Permissions.
You can select multiple items in Explore and apply permissions.
In the Permissions dialog box, select the users, groups, and roles to which you want to apply permissions
Permissions can be applied only to items to which a user has Full Control permission.
To populate the list with all users, groups, or roles, select Update List.
To filter the list, select begin with, contain, or are in group, then enter the filter criteria, and then click Update List.
If all of the artifacts are not listed, filter the list with criteria or contact your administrator. Your administrator determines the maximum number of artifacts to list. Wild cards are not supported and the filter is not case sensitive.
Move the desired users, groups, and roles to Selected Users, Groups and Roles.
From Selected Users, Groups and Roles, select a name in the Name column, and then click under the Access column to access a drop-down where you can select one of the following permissions:
Full Control
Modify
View
No Access
Optional: Depending on whether you are defining permissions for folders or files, select either Make these the default permissions for all folders I create or Make these the default permissions for all files I import to apply the permissions to other folders or imported content by default.
