Can I give CloudFiles access to a specific folder instead of the entire Drive or SharePoint?

yes, cloudfiles supports restricted access cloudfiles connects to external storage platforms (such as sharepoint, google drive, dropbox, etc ) using the user credentials provided during integration the access level cloudfiles has is entirely dependent on the permissions assigned to those credentials in other words, cloudfiles can only view or manage the files and folders that the connected user account is permitted to access for example, if you're integrating with sharepoint , and the connected user has access to only a specific site or folder, then cloudfiles will only surface those specific contents steps to grant access create a dedicated sharepoint user assign appropriate permissions to the specific site(s) or folder(s) connect this user to the cloudfiles interface during the integration process
