The IMSCC format is Instructure's own preferred file format, so I understand. There is very little information about how it compresses files, so for you to get as far as you have, if the rest of the file is readable is quite impressive, so very well done, Janaka. There is a whole range of issues around using that format, from essential corruption to deliberate damaging, to potential hardware issues that make it a file format that is pretty questionable. So far, AFAIK
, there has been no methodology to determine how to convert an IMSCC file to a zip file, or to how retain correctly formatted URLs. The URL
you have given is an alias, so the trick would be how to standardize that alias prior to uploading the course. I don't know of anyone who has even tried before.
Sorry, I can't be of much help, but without having someone to show the way, it is hard to know how something like this can be done, quickly and efficiently. You are at the very forefront of this movement, it's you who will likely by showing us how it can be done. There are a lot of people here who could help, but like you, they too will likely be shooting in the dark. Thank you for making the effort and very best wishes for your success.
