Tim,
Thanks for your reply.
"...and I am not sure there is a good answer at the moment."
I was afraid that might be the answer.
"On the other hand, what you are doing is clearly a highly practical way to create questions, and something like that should be made to work."
Yes, the GIFT format has saved me many hours of work. The ability to add URLs to questions in GIFT files means that in 1.9 I can create and upload 100's of listening questions without having to manually link each question to its respective sound file. The same goes for any 'media' file, and of course includes URLs in feedback too.
So while I fully understand that the new file system is better, it seems a pity that this extremely useful and time saving feature of GIFT (the ability to add URLs to multimedia) appears to have been rendered almost impossible in version 2.
Your suggested solution makes a lot of sense. Would it be worthwhile me 'creating an issue' (an 'improvement') in the tracker?
