Normally this is unchecked. **Direct Mode** – Data is uploaded and downloaded directly to and from the storage node and not via the portal. If direct mode is defined for the storage node, CTERA recommends setting the deduplication method to fixed blocks and keeping the default 4MB fixed block size. For details, see [Default Settings for New Folder Groups](/v1/docs/configuring-default-settings-for-virtual-portals-2#default-settings-for-new-folder-groups). **Note** Once **Direct Mode** is set, the **Use HTTPS** option is also checked and cannot be unchecked. **Use S3 Object Lock** – For future use.
