Working with the file system
var fileRef:FileReference = new FileReference();
fileRef.addEventListener(Event.SELECT, selectHandler);
fileRef.addEventListener(Event.COMPLETE, completeHandler);
try
{
var success:Boolean = fileRef.browse();
}
catch (error:Error)
{
trace("Unable to browse for files.");
}
function selectHandler(event:Event):void
{
var request:URLRequest = new URLRequest("http://www.[yourdomain].com/fileUploadScript.cfm")
try

You can send data to the server with the FileReference.upload() method by using the URLRequest.method and
URLRequest.data properties to send variables using the POST or GET methods.
When you attempt to upload a file using the FileReference.upload() method, the following events are dispatched:
open event (Event.OPEN): Dispatched when the upload operation starts.
progress event (ProgressEvent.PROGRESS): Dispatched periodically as bytes of data from the file are uploaded.
complete event (Event.COMPLETE): Dispatched when the upload operation completes successfully.
httpStatus event (HTTPStatusEvent.HTTP_STATUS): Dispatched when the upload process fails because of an
HTTP error.
httpResponseStatus event (HTTPStatusEvent.HTTP_RESPONSE_STATUS): Dispatched if a call to the upload()
or uploadUnencoded() method attempts to access data over HTTP and Adobe AIR is able to detect and return the
status code for the request.
securityError event (SecurityErrorEvent.SECURITY_ERROR): Dispatched when an upload operation fails
because of a security violation.
uploadCompleteData event (DataEvent.UPLOAD_COMPLETE_DATA): Dispatched after data is received from the
server after a successful upload.
ioError event (IOErrorEvent.IO_ERROR): Dispatched if the upload process fails for any of the following reasons:
An input/output error occurred while Flash Player is reading, writing, or transmitting the file.
The SWF tried to upload a file to a server that requires authentication (such as a user name and password).
During upload, Flash Player does not provide a means for users to enter passwords.
The url parameter contains an invalid protocol. The FileReference.upload() method must use either
HTTP or HTTPS.
