Question details

The user needs to restrict access to a main SharePoint folder while granting external users or volunteers access only to designated subfolders.

How to Restrict SharePoint Files While Allowing Subfolder Access

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Sharing specific subfolders with an external group without exposing internal documents located in the parent directory.
Observed behavior: By default, SharePoint inherits folder permissions, meaning users with access to the parent folder automatically receive access to all subfolders unless inheritance is manually broken.

Before you start

Ensure you have Site Owner or Full Control permissions for the SharePoint document library, as these are required to modify access settings and break permission inheritance.

Solution 1Recommended

Configure Unique Permissions for the Subfolder

Stop permission inheritance on the specific subfolder to remove unwanted parent-level access and grant explicit permissions to your target group.

To allow specific users into a subfolder without giving them access to the parent folder, you must break the default permission inheritance. This isolates the subfolder's security settings so you can customize exactly who can view or edit its contents.

Navigate to the subfolder

Open the SharePoint document library and locate the specific volunteer or target subfolder you want to share.

Access advanced permission settings

Select the subfolder, open the Details pane on the right side of the screen, click 'Manage access', and then select 'Advanced'.

Break inheritance

In the Advanced permissions ribbon, click 'Stop Inheriting Permissions'. This severs the link with the parent folder's security settings.

Remove unauthorized groups

Select the checkboxes next to any internal users or groups that should not have access to this specific subfolder, then click 'Remove User Permissions'.

Grant specific access

Click 'Grant Permissions' in the ribbon. Enter the names or email addresses of the volunteer group, select their required permission level (such as Read or Edit) from the options, and click 'Share'.

Configure Unique Permissions for the Subfolder

Manage Permissions Carefully: While breaking permission inheritance solves this specific access issue, doing it excessively across hundreds of folders can make site administration, auditing, and maintenance difficult. Use unique permissions only when necessary.

Frequently Asked Questions

Why can volunteers see the parent folder name when I only shared the subfolder?

When you grant access to a subfolder, SharePoint automatically grants 'Limited Access' to the parent folder. This simply allows the user to navigate the directory path to reach their subfolder. They cannot see or open any files located directly in the parent folder.

How do I restore permission inheritance if I make a mistake?

Go to the subfolder's Advanced permissions page (via Manage Access > Advanced) and click 'Delete unique permissions' in the ribbon. This will erase all custom access settings and immediately reconnect the folder to its parent's permission structure.

Can I hide the subfolder entirely from internal users who shouldn't see it?

Yes. Once you click 'Stop Inheriting Permissions' on the subfolder, you can select the internal users or groups from the list and click 'Remove User Permissions'. The folder will become completely invisible to them in the document library.
