## Configure file metadata Two elements of the metadata are configurable: file format and what's in the file. You configure each of these in difference places in Airbyte. ### Change the metadata format {#metadata-format} To change the format of the metadata, change the output format on the Destination connector. 1. In the left navigation, click **Destinations**. 2. Choose your destination connector from the list, or [create a new one](getting-started/add-a-destination). 3. Under **Output Format**, choose the file format you want. You can also choose whether you want to compress the file, or if you want to flatten it. ![Choosing JSON Lines format as the Output Format on the Destinaton configuration for the S3 destination](images/output-format.png) 4. Click **Test and save**. Next time you sync, your metadata has the chosen format. ### Change what's in the metadata {#metadata-content} You choose what appears in your metadata when setting up your connection. 1. In the left navigation, click **Connections**. 2. Choose your connection from the list, or [create a new one](getting-started/set-up-a-connection). 3. Click the **Schema** tab. 4. Open the stream that contains your files. 5. Select and deselect fields as needed. ![article_attachments stream with various fields selected and deselected](images/file-metadata-choice.png) 6.
