Correctly exported DICOM will result in hundreds of DICOM files contained inside a folder. Export STL files as "File Per Arch (arches oriented in occlusion)", Both the DICOM folder (containing many files) and the U and L STL files should be placed into a folder titled as the patient's name. Zip that folder (right click, send to compressed folder) then click add file and upload it. You will only be allowed to upload the one zipped file.
