# Managing Collaborators

Learn how to control access to your content, view Box items that reference your files and folders, and manage collaboration settings.

## Modifying Collaborator Access Levels

If you are an editor, owner, or co-owner of a file or folder, you can modify the access levels of other collaborators.

**To modify a collaborator's access level in a folder:**

* Open the appropriate folder.
* In the right sidebar, select the **Sharing** tab to view the collaborators.
* Select a collaborator's name to view all collaborators in the folder.
* Find the collaborator whose access level you want to modify. To search by name, use the **Filter Collaborators** search box in the upper-right corner.
* In the **Permissions** column, select the user's access level, then select the appropriate access level from the menu. If the access level is unavailable, you may not have permission to modify it.

> [!NOTE]
>
> The **Sharing** tab in the right sidebar lists all users and groups that have access to a folder, including deactivated users.

![Sharing sidebar listing collaborators and their access levels](https://mintcdn.com/product-docs/Z6GH5HR7q80QNRdI/images/box-fundamentals/admin-console-manage-collabs.png?fit=max\&auto=format\&n=Z6GH5HR7q80QNRdI\&q=85\&s=7b091d1431e962c37243e479a2191f64)

**To modify a collaborator's access level in a single file:**

* Locate the appropriate file.
* Select the **Collaboration** icon ![Person with a plus sign](https://docs.box.com/images/box-fundamentals/sfc-2.png) to the right of the file name.
* Alternatively, you can open **More Options** > **More Actions** and select **Manage Collaborators**.
* Find the collaborator whose access level you want to modify. To search by name, use the **Filter Collaborators** search box in the upper-right corner.
* In the **Permissions** column, select the user's access level, then select the appropriate access level from the menu. If the access level is unavailable, you may not have permission to modify it.

> [!NOTE]
>
> Collaborators on individual files can have only **Editor** or **Viewer** access.

## Viewing references

The **References** tab on the **Collaborators** page lists every Box item that references a file or folder. A Box item is a file, folder, Hub, Automate workflow, Extract Agent, or web link. People and groups with direct access to the file or folder remain on the **People & Groups** tab.

![References tab on the Collaborators page listing Box items that reference a folder, with columns for name, collaborators, permissions, date added, access via, and owner or co-owners.](https://mintcdn.com/product-docs/HJspGnSkt4lh09XL/images/box-fundamentals/References_page.png?fit=max\&auto=format\&n=HJspGnSkt4lh09XL\&q=85\&s=a20f5efe8585bf19b0e0c07e0ed03c00)

**To view references:**

1. Open the file or folder. On the **Sharing** tab in the right sidebar, locate the **References** count. The count indicates how many Box items reference the file or folder.
2. Select the **References** count ![References count in the Sharing sidebar, shown as plus 35 References.](https://docs.box.com/images/box-fundamentals/References-icon.png). The **References** tab on the **Collaborators** page opens.
3. Select the name of a Box item to open it.

The **References** tab displays the following details for each Box item:

* **Name:** The type and name of the Box item that references your file or folder.
* **Collaborators:** The number of people and groups with access through that Box item, and the number of references the Box item contains.
* **Permissions:** The access level that collaborators on the Box item have to your file or folder.
* **Date added:** The date your file or folder was added to the Box item.
* **Access via:** The file or folder the Box item references. This is either the file or folder you opened, or a parent folder that passes access down to it.
* **Owner/Co-owners:** The people who manage the Box item. Hover over an avatar to view a name. If no owner or co-owner is available, this column displays **None**.

> [!NOTE]
>
> Box items you do not have permission to view display a generic name, such as **Private Hub**, **Private Workflow**, or **Private Item**.

## Removing Item References

Content owners and co-owners can remove a file or folder from any Box item that references it, including [Box Hubs](https://docs.box.com/en/box-hubs/box-hubs-for-admins/about-box-hubs.md). This gives you more control over your content and helps keep sensitive or regulated content from remaining visible in Box items where it should not be.

**To remove an item reference:**

1. Open the file or folder. On the **Sharing** tab in the right sidebar, locate the **References** count.
2. Select the **References** count ![References count in the Sharing sidebar, shown as plus 35 References.](https://docs.box.com/images/box-fundamentals/References-icon.png). The **References** tab on the **Collaborators** page opens.
3. Find the Box item you want to remove the file or folder from.
4. Select **Remove** next to the item name, then confirm the action.

After you remove the reference, the file or folder is no longer accessible in that Box item.

> [!NOTE]
>
> If a Box item references folders at multiple levels of a hierarchy (for example, a grandparent folder, a parent folder within it, and files within the parent folder), removing a file reference does not remove access to the file if any of its parent folders remain referenced.

## Transferring folder ownership

If you own a folder, you can transfer ownership to a collaborator at any time. Follow the instructions for modifying access levels, then select **Owner** from the access level menu. Only folder owners can view this option. The collaborator becomes the folder owner, your access level changes to **Editor**, and the folder contents no longer count against your account's storage allowance.

Before transferring a [personal folder](https://docs.box.com/en/box-fundamentals/for-users/staying-organized/organizing-and-tracking-content/understanding-folder-icons-and-colors.md) (a folder with no collaborators), invite the new owner to collaborate on it. For larger transfers, we recommend completing the transfer at the end of the day to avoid disrupting users. If you experience issues, submit a [Box support case](https://support.box.com/hc/en-us/articles/360043693474). If the new owner belongs to a different enterprise, Box clears any [custom shared link URLs](https://docs.box.com/en/box-admin-tools/how-to-guides-for-admins/shared-links-settings-for-your-enterprise.md).

If you move a folder you own into a folder owned by someone else, ownership of the moved folder transfers to the owner of the destination folder. For example, if you move Folder A into Folder B, the owner of Folder B becomes the owner of Folder A.

You can transfer folder ownership only to a user who is a direct collaborator on the folder. For example, if you invite a user to Folder A, which contains Folder A-1, the user inherits access to Folder A-1. You can transfer Folder A to the user, but you cannot transfer Folder A-1 because the user is not a direct collaborator on it.

When you transfer folder ownership, Box displays the following warning:

![Change Item Owner confirmation dialog with Cancel and Okay options](https://mintcdn.com/product-docs/WyLQ6oIDXM_KHq6W/images/box-fundamentals/change-item-owner.png?fit=max\&auto=format\&n=WyLQ6oIDXM_KHq6W\&q=85\&s=4100b12a900f2c74b09e876a27cec1a3)

Box displays this generic warning for ownership transfers at any folder level, including root-level folders and subfolders. It does not mean that collaborators always lose access. When you transfer a subfolder, users whose access is inherited from a parent folder may lose access because the subfolder leaves the original parent folder structure.

This issue does not apply to a root-level folder because it has no parent folder. Box still displays the standard warning, but other permissions remain unchanged.

To transfer ownership of a folder to a [service account](https://developer.box.com/platform/user-types/#service-account), use the [Box API](https://developer.box.com/guides/folders/single/change-owner/).

## Removing collaborators

If you are an editor, owner, or co-owner of a folder, you can remove collaborators from it.

**To remove a collaborator from a folder:**

* Open the appropriate folder.
* View the list of collaborators in the right sidebar.
* Select a collaborator's name to view all collaborators in the folder.
* Find the collaborator you want to remove. To search by name, use the **Filter Collaborators** search box in the upper-right corner.
* In the **Permissions** column, select the user's access level, then select **Remove**. If the option is unavailable, you may not have permission to remove that collaborator.

**To remove a collaborator from a single file:**

* Locate the appropriate file.
* Select the **Collaboration** icon ![Person with a plus sign](https://docs.box.com/images/box-fundamentals/sfc-2.png) to the right of the file name.
* Alternatively, you can open **More Options** > **More Actions** and select **Manage Collaborators**.
* Find the collaborator you want to remove. To search by name, use the **Filter Collaborators** search box in the upper-right corner.
* In the **Permissions** column, select the user's access level, then select **Remove**. If the option is unavailable, you may not have permission to remove that collaborator.

## Hiding Collaborators

Folder owners and co-owners can hide collaborators. When this setting is enabled, collaborators with **Editor** access or lower cannot view the names of other collaborators in the folder. Co-owners can still view all collaborators. Box replaces hidden names with **Someone**.

> [!WARNING]
>
> * To protect the identities of non-owner collaborators, [disable comments](https://docs.box.com/en/box-fundamentals/for-users/staying-organized/managing-files-and-folders/box-folder-settings.md) in **Folder Settings** and enable **Hide collaborators**.
> * This feature does not anonymize names in **Version History**. Other collaborators can view the names of non-owner collaborators who upload new file versions.
> * Collaborators can still use [tasks](https://docs.box.com/en/box-fundamentals/for-users/collaborating/sharing-content-using-box/adding-comments-and-tasks.md).
> * With this setting enabled, collaborators in the affected folder cannot use Microsoft Office Online or Box for Microsoft Office Co-Authoring to open Office files in the folder.

To hide collaborators:

1. Right-click the folder, or select the **ellipsis** (**...**), to open the **More Options** menu.
2. Select **Settings** to open **Folder Settings**.
3. In the **Privacy** section, select **Hide collaborators and their activity from non-owners**.

   ![Privacy settings with Hide collaborators and their activity from non-owners selected](https://mintcdn.com/product-docs/Qyy8LmrN0pVKQFf5/images/box-fundamentals/hide-collaborators-boxed.png?fit=max\&auto=format\&n=Qyy8LmrN0pVKQFf5\&q=85\&s=03497a513233b4d2284b70611587b9ee)

From this page, you can also restrict who can send invitations and collaborate in the folder. For details, see [Folder settings](https://docs.box.com/en/box-fundamentals/for-users/staying-organized/managing-files-and-folders/box-folder-settings.md).

## Collaborator Auto-Expiration

> [!NOTE]
>
> * Collaborator auto-expiration applies to individual collaborators, but not to [groups](https://docs.box.com/en/box-admin-tools/managing-box-users-and-admins/groups/creating-and-managing-groups.md). When you add a group as a collaborator, a clock icon can display next to the group name, but auto-expiration does not apply to the group.
> * The collaboration can be auto-deleted prior to the expiration date if 30 days have passed after the collaboration was set to pending status. More information is available [here](https://support.box.com/hc/en-us/articles/360044196073-Collaboration-Frequently-Asked-Questions#01JG0BD3832V3MKEAFJZRBR3BQ).

> [!WARNING]
>
> To enable collaboration auto-expiration, enable **Automatically remove invited collaborators** in **Admin Console** > **Enterprise Settings**. If the setting is disabled, you cannot create or modify collaborator expirations. For details, see [Invited collaborator expiration settings](https://support.box.com/hc/en-us/articles/4404822772755-Enterprise-Settings-Content-Sharing-Tab/#Invited_collaborators_expiration_settings).

Depending on your organization's enterprise settings, collaborator access to a folder can expire after a specific period. If a collaborator is set to auto-expire, a **clock** icon displays beside their name in the right sidebar on the **Sharing** tab. Hover over the icon to view the expiration date.

![Sharing sidebar with a clock icon beside a collaborator](https://mintcdn.com/product-docs/eEZ2SZ8FKaSHD273/images/box-fundamentals/autoexpire-amst-1.png?fit=max\&auto=format\&n=eEZ2SZ8FKaSHD273\&q=85\&s=3f2bd48bb72fd5f8439e21d7b48f5a67)

Before a collaboration expires, Box sends email notifications to the folder owner and co-owners if notifications are enabled in your organization's enterprise settings. Box notifies only co-owners who collaborate directly on the item with a pending expiration, not co-owners with inherited permissions.

### Extending collaborator auto-expiration

Folder owners can extend a collaborator's auto-expiration date.

To extend a collaborator's auto-expiration date:

* Select a collaborator's name to open the **Collaborator Management** page. Alternatively, select the **folder name** in the folder tree, then select **More Options** > **More Actions** > **Manage Collaborators**.

![Collaborator Management page listing names and access levels](https://mintcdn.com/product-docs/iPwbarrlsv1nexQc/images/box-fundamentals/autoexpire-amst-3.png?fit=max\&auto=format\&n=iPwbarrlsv1nexQc\&q=85\&s=088b39090a9a5c460319f891bd17ce6e)

* Select the **clock** icon beside the collaborator whose auto-expiration date you want to extend. To filter a long list of collaborators, use the search bar in the upper-right corner.
* Select **Extend Access**.

![Extend Access dialog with a new expiration date](https://mintcdn.com/product-docs/iPwbarrlsv1nexQc/images/box-fundamentals/autoexpire-amst-2.png?fit=max\&auto=format\&n=iPwbarrlsv1nexQc\&q=85\&s=7e3683b8d860bf50927b63bc69ff886a)

* A confirmation message displays the new expiration date.
