Using the File System API

A URI scheme is specified at the beginning of a URL, such as file in the following example:

  file:///c:/ApolloTest/test.txt

In addition to thefileURI scheme, Apollo supports the new URI schemesapp-storageand
app-resource.

Identifies the application storage directory, as shown in the following example:

  var logFile:File = File.appStorageDirectory;
  logFile = logFile.resolve("log.txt");
  trace(logFile.url); // app-storage:/log.txt

Identifies this application’s installation folder, as in the following:

  var installDir:File = new File();
  installDir.url = "app-resource:/";
  installDir = installDir.resolve("HelloWorld-app.xml");
  trace(installDir.url); // app-resource:/HelloWorld-app.xml

The url property of otherFileobject returns a standardfileURL scheme:

  var file:File = File.documentsDirectory;
  file = file.resolve("ApolloTest/test.txt");
  trace(file.url);
    // On Windows:
    // file:///C:/Documents%20and %20Settings/ ... /test.txt
    // On Mac OS:
    // file:///Users/userName/Documents/ ... /test.txt
