## Previewing a file To view the file content: 1. Click **Browse**. 2. Select the lakehouse where the source files are located. 3. In the source lakehouse, navigate to the file.

## Configuring entity type handling On the **Entity types from scanned files** page, for each entity type, you configure how the detected values appear in the redacted files. By default, the handling option is **Off**, which means that the values are not replaced, and remain as is in the output files. The other options are: * **Redaction -** Replaces each value with the name of the entity type, followed by a unique identifier for the value. For example, the name `John` is replaced with something like `[NAME_GIVEN_ab15c7]`. * **Synthesis -** Replaces each value with a different realistic value. For example, the name `John` is replaced with `Michael`. ### Selecting the handling option for a specific entity type To select the handling option for a specific entity type: 1. In the **Configuration** column, click the dropdown for the entity type. 2. From the dropdown list, select the handling option. ### Assigning the same handling option to all of the entity types To assign the same handling option to all of the entity types: 1.
