File/Attachment Sync takes files that are uploaded to Salesforce Files or Salesforce Attachments and syncs them with S-Drive for the selected object. Sync is processed based on a queue, so new items will appear in S-Drive in a few seconds/minutes.
Since files uploaded to Chatter are also Salesforce Files, these are synced to S-Drive as well. If you have “delete after sync” enabled, a comment will be posted to Chatter to let users know the file has been synced to S-Drive.
Once you configure File/Attachment Sync with S-Drive, you can start using File/Attachment Sync features. See File/Attachment Sync to configure this feature.
