# Overriding the project entity type configuration

By default, each file in a project uses the [project-wide settings for Textual entity types](/textual/guided-redaction/redaction-project-create-manage/enabling-and-disabling-entity-types-and-values.md). The entity type settings include:

* Whether each entity type is enabled. You can enable or disable both built-in and regex-based custom entity types. You cannot enable model-based custom entity types. When you disable an entity type, values of that type are ignored by the Textual scan.
* For each built-in entity type, added and excluded values.

Within a file, you can override the project settings. When you save the new settings, Textual automatically rescans the file to change the detected entities based on the new settings.

## **Displaying the file-specific entity type settings**

To display the file-specific entity type settings, either:

* On the details panel for a redaction, click the settings icon.
* In the file header, click **More**, then click **File-specific entity detection settings**.

## **Enabling and disabling entity types**

To enable an entity type, set the entity type toggle to the on position.

To disable an entity type, set the toggle to the off position.

## **Adding and excluding values for a built-in entity type**

To display the panel to add and exclude values, click the add or exclude values icon.

On the panel:

* Use the **Add to detection** tab to add values.
* Use the **Remove from detection** tab to remove values.

Each value can be either a specific word or phrase to add or exclude, or a regular expression to identify the values to add or exclude. Regular expressions must be C# compatible.

## **Saving and updating the detection based on the changes**

When you finish the configuration changes, click **Save**.

Textual rescans the file and changes the detected entities based on the new settings.

For example, the initial scan detected a Given Name value. You change the file-specific settings to disable the Given Name entity type. After the new scan, the value is no longer highlighted.
