Storyline file size

Hi, similar problem though happening from a different angle, I guess.

I've been focused on minimising the size of a specific output file when you publish for HTML5 (paths.js) as in testing the size of this file (and hence the unexpectedly long download time) was causing the course launch to time out within strictly managed networks.

So after publishing I habitually check the paths.js file. What I noticed was that when I imported all the slides into a new empty course (to shake off some file corruption that seemed to be creeping in - "this project is locked by another process") that paths.js file had dramatically increased in size from 3.2MB to 5.6MB even though nothing content- or navigation-wise had changed.

It's almost as if the import brought some large component of the existing information with it then "forgot" it had it and re-created it again. Digging a bit deeper I found some sub-files within the .story container itself that definitely contained "historical" content that was no longer in the course - specifically summary.xml within docProps. Further, that historical content was more than a few save, close and restarts ago, in fact it predated the import, so should presumably have been purged a while back?

Another interesting wrinkle is that the summary.xml file showed my slide and navigation count as 440 - exactly double the number of slides I thought I had!

Any thoughts?

Thanks

Matt
