The SCORM files will contain the following file ‘imsmanifest.xml’. However, your LMS may report this file as missing if the SCORM file is inside another zip folder.
The SCORM files all have a version number such as v3.0.0.
If you are trying to upload a zip file that doesn’t have a version number, please unzip this folder and upload the individual or single SCORM(s) inside this folder.
