<p>The application's <em>Temp</em> folder is a unique application-specific folder, intended to store any temporary files that the application may need. It will be created when this function is called for the first time (lazy initialization); subsequent calls are guaranteed to return the same path. Usually the application's <em>Temp</em> folder will be created as a sub-folder of the system's global <em>Temp</em> folder, as indicated by the <code>TMP</code> or <code>TEMP</code> environment variables. However, it may be created at a different place (e.g. in the users <em>Profile</em> directory), if those environment variables don't point to a usable directory. In any case, this function makes sure that the application's <em>Temp</em> folder exists for the whole lifetime of the application and that it is writable. When the application is about to terminate, the application's <em>Temp</em> folder and all files or sub-directories thereof will be <em>removed</em> automatically!</p>
