That's fine, it only needs to be there temporarily while the app runs. 
The app can test to see if the file exists if it needs it again, and 
recopy it.

I need to put html stored in a custom property into a browser object. 
Since using a variable isn't possible, I need to write the property to 
disk and then load it.

A URL from the server would work too, and I'll do that if we need to, 
but I wanted to explore the idea of using the temp folder instead so I 
can store the html data in the stack. But the temporary folder has to be 
reliably accessible to do that.
