I had a map open, then I moved the SCM file, and now StarEdit says it can save my file. Why?
StarEdit uses data files more like a database than a traditional program. Specifically, StarEdit does not maintain all the data for the scenario in memory, which would allow it to completely recreate the file every time you saved. This would be impossible due to the fact that you can imports sounds into your scenarios, and StarEdit cannot assume that there is enough RAM on your system to hold all the imported sounds in memory. So sounds are imported directly into the file, and only the reference to the sound kept in memory. Because of this, if the file is moved or deleted while StarEdit is running, it cannot save a new copy of the scenario that will work correctly if the database file with all imported sounds is missing. So the answer is, “Don’t do that.
