Digital Workshop

I've published on the web in a Opus pro publication (a course).
When i run the publication from the web then a file ild.temp is stored in "local settings/temp" in explorer on the local machine. By closing the publication this file is still there.
Every time I open the publication on the web there is another new ilm.temp file stored in this map.
So, when someone followed a course on the web this map will be filled with as many ilm.temp as the student has logged in.
Is there a solution to automaticlly clean up this map when the publication is closed.
