If a file storage company that claims to be protecting users' data isn't storing it in an encrypted manner that requires people to jump through all manner of technical and proceduraly hoops to get access to them, then they are failing quite badly.
Whatever encryption is there (and we don't know what they are doing in this respect), their staff who manage the systems still have access to look up the file name of the Xth file, or if they like to go snooping through all files.
