rootDirectory

The directory within the Amazon S3 Files file system to mount as the root directory. If this parameter is omitted, the root of the Amazon S3 Files file system will be used. Specifying / will have the same effect as omitting this parameter.

If a S3 Files access point is specified in the accessPointArn, the root directory parameter must either be omitted or set to / which will enforce the path set on the S3 Files access point.
