ACTIONSCRIPT 3.0 DEVELOPER’S GUIDE
Working with the file system
The “Async” versions of the copy and move methods work asynchronously. Use the addEventListener() method to
monitor completion of the task or error conditions, as in the following code:
var original = File.documentsDirectory;
original = original.resolvePath("AIR Test/test.txt");
var destination:File = File.documentsDirectory;
destination = destination.resolvePath("AIR Test 2/copy.txt");
original.addEventListener(Event.COMPLETE, fileMoveCompleteHandler);
original.addEventListener(IOErrorEvent.IO_ERROR, fileMoveIOErrorEventHandler);
original.moveToAsync(destination);
function fileMoveCompleteHandler(event:Event):void {
trace(event.target); // [object File]
}
function fileMoveIOErrorEventHandler(event:IOErrorEvent):void {
trace("I/O Error.");
}
The File class also includes the File.moveToTrash() and File.moveToTrashAsync() methods, which move a file
or directory to the system trash.
Deleting a file
Adobe AIR 1.0 and later
The File class includes a deleteFile() method and a deleteFileAsync() method. These methods delete files, the
first working synchronously, the second working asynchronously (see “AIR file basics” on page 666).
For example, the following code synchronously deletes the test.txt file in the user's documents directory:
var file:File = File.documentsDirectory.resolvePath("test.txt");
file.deleteFile();
The following code asynchronously deletes the test.txt file of the user's documents directory:
var file:File = File.documentsDirectory.resolvePath("test.txt");
file.addEventListener(Event.COMPLETE, completeHandler)
file.deleteFileAsync();
function completeHandler(event:Event):void {
trace("Deleted.")
}
Also included are the moveToTrash() and moveToTrashAsync methods, which you can use to move a file or directory
to the System trash. For details, see “Moving a file to the trash” on page 685.
Moving a file to the trash
Adobe AIR 1.0 and later
The File class includes a moveToTrash() method and a moveToTrashAsync() method. These methods send a file or
directory to the System trash, the first working synchronously, the second working asynchronously (see “AIR file
basics” on page 666).
