You can add iSpring-generated course into Moodle as a Flash file or as a SCORM package.
1. If you want to upload a SWF file, you can generate an all-in-one flash movie. To do it, please open Publish dialog, check "All in one Flash file" option in General tab, uncheck "Generate HTML", then go to the Advanced tab and uncheck all checkboxes in the "Detach media content" group. In this case you'll get 1 SWF-file after conversion. then you can upload it to Moodle.
2. To create a SCORM package, please open the Publish dialog, select "LMS" as the publish destination in the left menu, enable the "Zip output" option, select the Learning Course tab and set the required course settings. iSpring will generate one zip-archive with your course inside. Add it to Moodle as a SCORM/AICC resource.
