The creation date of the file on the local disk. If the object is was not populated, a call to get the value of this property returns null.

See also

The Macintosh creator type of the file, which is only used in Mac OS versions prior to Mac OS X. In Windows or Linux, this property is null. If the FileReference object was not populated, a call to get the value of this property returns null.

See also

The ByteArray object representing the data from the loaded file after a successful call to the load() method.

See also

The filename extension.

A file's extension is the part of the name following (and not including) the final dot ("."). If there is no dot in the filename, the extension is null.

Note: You should use the extension property to determine a file's type; do not use the creator or type properties. You should consider the creator and type properties to be considered deprecated. They apply to older versions of Mac OS.

The date that the file on the local disk was last modified. If the FileReference object was not populated, a call to get the value of this property returns null.

See also

The name of the file on the local disk. If the FileReference object was not populated (by a valid call to FileReference.download() or FileReference.browse()), Flash Player throws an error when you try to get the value of this property.

All the properties of a FileReference object are populated by calling the browse() method. Unlike other FileReference properties, if you call the download() method, the name property is populated when the select event is dispatched.

See also

The size of the file on the local disk in bytes. If size is 0, an exception is thrown.

Note: In the initial version of ActionScript 3.0, the size property was defined as a uint object, which supported files with sizes up to about 4 GB. It is now implimented as a Number object to support larger files.

See also

The file type.

In Windows or Linux, this property is the file extension. On the Macintosh, this property is the four-character file type, which is only used in Mac OS versions prior to Mac OS X. If the FileReference object was not populated, a call to get the value of this property returns null.

For Windows, Linux, and Mac OS X, the file extension — the portion of the name property that follows the last occurrence of the dot (.) character — identifies the file type.

See also

Creates a new FileReference object. When populated, a FileReference object represents a file on the user's local disk.

See also

Displays a file-browsing dialog box that lets the user select a file to upload. The dialog box is native to the user's operating system. The user can select a file on the local computer or from other systems, for example, through a UNC path on Windows.

Note: The File class, available in Adobe AIR, includes methods for accessing more specific system file selection dialog boxes. These methods are File.browseForDirectory(), File.browseForOpen(), File.browseForOpenMultiple(), and File.browseForSave().

When you call this method and the user successfully selects a file, the properties of this FileReference object are populated with the properties of that file. Each subsequent time that the FileReference.browse() method is called, the FileReference object's properties are reset to the file that the user selects in the dialog box. Only one browse() or download() session can be performed at a time (because only one dialog box can be invoked at a time).

Using the typeFilter parameter, you can determine which files the dialog box displays.

In Flash Player 10 and Flash Player 9 Update 5, you can only call this method successfully in response to a user event (for example, in an event handler for a mouse click or keypress event). Otherwise, calling this method results in Flash Player throwing an Error exception.

Note that because of new functionality added to the Flash Player, when publishing to Flash Player 10, you can have only one of the following operations active at one time: FileReference.browse(), FileReference.upload(), FileReference.download(), FileReference.load(), FileReference.save(). Otherwise, Flash Player throws a runtime error (code 2174). Use FileReference.cancel() to stop an operation in progress. This restriction applies only to Flash Player 10. Previous versions of Flash Player are unaffected by this restriction on simultaneous multiple operations.

Parameters

See also

Cancels any ongoing upload or download operation on this FileReference object. Calling this method does not dispatch the cancel event; that event is dispatched only when the user cancels the operation by dismissing the file upload or download dialog box.

Opens a dialog box that lets the user download a file from a remote server. Although Flash Player has no restriction on the size of files you can upload or download, the player officially supports uploads or downloads of up to 100 MB.

The download() method first opens an operating-system dialog box that asks the user to enter a filename and select a location on the local computer to save the file. When the user selects a location and confirms the download operation (for example, by clicking Save), the download from the remote server begins. Listeners receive events to indicate the progress, success, or failure of the download. To ascertain the status of the dialog box and the download operation after calling download(), your code must listen for events such as cancel, open, progress, and complete.

The FileReference.upload() and FileReference.download() functions are nonblocking. These functions return after they are called, before the file transmission is complete. In addition, if the FileReference object goes out of scope, any upload or download that is not yet completed on that object is canceled upon leaving the scope. Be sure that your FileReference object remains in scope for as long as the upload or download is expected to continue.

When the file is downloaded successfully, the properties of the FileReference object are populated with the properties of the local file. The complete event is dispatched if the download is successful.

Only one browse() or download() session can be performed at a time (because only one dialog box can be invoked at a time).

This method supports downloading of any file type, with either HTTP or HTTPS.

You cannot connect to commonly reserved ports. For a complete list of blocked ports, see "Restricting Networking APIs" in the ActionScript 3.0 Developer's Guide.

Note: If your server requires user authentication, only SWF files running in a browser — that is, using the browser plug-in or ActiveX control — can provide a dialog box to prompt the user for a user name and password for authentication, and only for downloads. For uploads using the plug-in or ActiveX control, or for uploads and downloads using the stand-alone or external player, the file transfer fails.

When you use this method , consider the Flash Player security model:

• Loading operations are not allowed if the calling SWF file is in an untrusted local sandbox.
• The default behavior is to deny access between sandboxes. A website can enable access to a resource by adding a URL policy file.
• You can prevent a SWF file from using this method by setting the allowNetworking parameter of the the object and embed tags in the HTML page that contains the SWF content.
• In Flash Player 10 and Flash Player 9 Update 5, you can only call this method successfully in response to a user event (for example, in an event handler for a mouse click or keypress event). Otherwise, calling this method results in Flash Player throwing an Error exception.

However, in Adobe AIR, content in the application security sandbox (content installed with the AIR application) is not restricted by these security limitations.

For more information related to security, see the Flash Player Developer Center Topic: Security.

When you download a file using this method, it is flagged as downloaded on operating systems that flag downloaded files:

• Windows XP service pack 2 and later, and on Windows Vista
• Mac OS 10.5 and later

Some operating systems, such as Linux, do not flag downloaded files.

Note that because of new functionality added to the Flash Player, when publishing to Flash Player 10, you can have only one of the following operations active at one time: FileReference.browse(), FileReference.upload(), FileReference.download(), FileReference.load(), FileReference.save(). Otherwise, Flash Player throws a runtime error (code 2174). Use FileReference.cancel() to stop an operation in progress. This restriction applies only to Flash Player 10. Previous versions of Flash Player are unaffected by this restriction on simultaneous multiple operations.

}

Starts the load of a local file selected by a user. Although Flash Player has no restriction on the size of files you can upload, download, load or save, it officially supports sizes of up to 100 MB. For content running in Flash Player, you must call the FileReference.browse() or FileReferenceList.browse() method before you call the load() method. However, content running in AIR in the application sandbox can call the load() method of a File object without first calling the browse() method. (The AIR File class extends the FileReference class.)

Listeners receive events to indicate the progress, success, or failure of the load. Although you can use the FileReferenceList object to let users select multiple files to load, you must load the files one by one. To load the files one by one, iterate through the FileReferenceList.fileList array of FileReference objects.

Adobe AIR also includes the FileStream class which provides more options for reading files.

The FileReference.upload(), FileReference.download(), FileReference.load() and FileReference.save() functions are nonblocking. These functions return after they are called, before the file transmission is complete. In addition, if the FileReference object goes out of scope, any transaction that is not yet completed on that object is canceled upon leaving the scope. Be sure that your FileReference object remains in scope for as long as the upload, download, load or save is expected to continue.

If the file finishes loading successfully, its contents are stored as a byte array in the data property of the FileReference object.

The following security considerations apply:

• Loading operations are not allowed if the calling SWF file is in an untrusted local sandbox.
• The default behavior is to deny access between sandboxes. A website can enable access to a resource by adding a cross-domain policy file.
• You can prevent a file from using this method by setting the allowNetworking parameter of the the object and embed tags in the HTML page that contains the SWF content.

However, these considerations do not apply to AIR content in the application sandbox.

Note that when publishing to Flash Player 10 or AIR 1.5, you can have only one of the following operations active at one time: FileReference.browse(), FileReference.upload(), FileReference.download(), FileReference.load(), FileReference.save(). Otherwise, the application throws a runtime error (code 2174). Use FileReference.cancel() to stop an operation in progress. This restriction applies only to Flash Player 10 and AIR 1.5. Previous versions of Flash Player or AIR are unaffected by this restriction on simultaneous multiple operations.

Opens a dialog box that lets the user save a file to the local filesystem. Although Flash Player has no restriction on the size of files you can upload, download, load or save, the player officially supports sizes of up to 100 MB.

The save() method first opens an operating-system dialog box that asks the user to enter a filename and select a location on the local computer to save the file. When the user selects a location and confirms the save operation (for example, by clicking Save), the save process begins. Listeners receive events to indicate the progress, success, or failure of the save operation. To ascertain the status of the dialog box and the save operation after calling save(), your code must listen for events such as cancel, open, progress, and complete.

Adobe AIR also includes the FileStream class which provides more options for saving files locally.

The FileReference.upload(), FileReference.download(), FileReference.load() and FileReference.save() functions are nonblocking. These functions return after they are called, before the file transmission is complete. In addition, if the FileReference object goes out of scope, any transaction that is not yet completed on that object is canceled upon leaving the scope. Be sure that your FileReference object remains in scope for as long as the upload, download, load or save is expected to continue.

When the file is saved successfully, the properties of the FileReference object are populated with the properties of the local file. The complete event is dispatched if the save is successful.

Only one browse() or save() session can be performed at a time (because only one dialog box can be invoked at a time).

In Flash Player, you can only call this method successfully in response to a user event (for example, in an event handler for a mouse click or keypress event). Otherwise, calling this method results in Flash Player throwing an Error exception. This limitation does not apply to AIR content in the application sandbox.

MyTextField.type = TextFieldType.INPUT;

MyButtonField.background = true;

MyButtonField.x = 150;
MyButtonField.height = 20;
MyButtonField.text = "Click here to save";

function clickhandler(e:MouseEvent): void {
    MyFile.save(MyTextField.text);
}

Starts the upload of the file to a remote server. Although Flash Player has no restriction on the size of files you can upload or download, the player officially supports uploads or downloads of up to 100 MB. You must call the FileReference.browse() or FileReferenceList.browse() method before you call this method.

For the Adobe AIR File class, which extends the FileReference class, you can use the upload() method to upload any file. For the FileReference class (used in Flash Player), the user must first select a file.

Listeners receive events to indicate the progress, success, or failure of the upload. Although you can use the FileReferenceList object to let users select multiple files for upload, you must upload the files one by one; to do so, iterate through the FileReferenceList.fileList array of FileReference objects.

The FileReference.upload() and FileReference.download() functions are nonblocking. These functions return after they are called, before the file transmission is complete. In addition, if the FileReference object goes out of scope, any upload or download that is not yet completed on that object is canceled upon leaving the scope. Be sure that your FileReference object remains in scope for as long as the upload or download is expected to continue.

The file is uploaded to the URL passed in the url parameter. The URL must be a server script configured to accept uploads. Flash Player uploads files by using the HTTP POST method. The server script that handles the upload should expect a POST request with the following elements:

• Content-Type of multipart/form-data
• Content-Disposition with a name attribute set to "Filedata" by default and a filename attribute set to the name of the original file
• The binary contents of the file

You cannot connect to commonly reserved ports. For a complete list of blocked ports, see "Restricting Networking APIs" in the ActionScript 3.0 Developer's Guide.

For a sample POST request, see the description of the uploadDataFieldName parameter. You can send POST or GET parameters to the server with the upload() method; see the description of the request parameter.

If the testUpload parameter is true, and the file to be uploaded is bigger than approximately 10 KB, Flash Player on Windows first sends a test upload POST operation with zero content before uploading the actual file, to verify that the transmission is likely to succeed. Flash Player then sends a second POST operation that contains the actual file content. For files smaller than 10 KB, Flash Player performs a single upload POST with the actual file content to be uploaded. Flash Player on Macintosh does not perform test upload POST operations.

Note: If your server requires user authentication, only SWF files running in a browser — that is, using the browser plug-in or ActiveX control — can provide a dialog box to prompt the user for a username and password for authentication, and only for downloads. For uploads using the plug-in or ActiveX control, or for uploads and downloads using the stand-alone or external player, the file transfer fails.

When you use this method , consider the Flash Player security model:

• Loading operations are not allowed if the calling SWF file is in an untrusted local sandbox.
• The default behavior is to deny access between sandboxes. A website can enable access to a resource by adding a URL policy file.
• You can prevent a SWF file from using this method by setting the allowNetworking parameter of the the object and embed tags in the HTML page that contains the SWF content.

However, in Adobe AIR, content in the application security sandbox (content installed with the AIR application) are not restricted by these security limitations.

For more information related to security, see the Flash Player Developer Center Topic: Security.

Note that because of new functionality added to the Flash Player, when publishing to Flash Player 10, you can have only one of the following operations active at one time: FileReference.browse(), FileReference.upload(), FileReference.download(), FileReference.load(), FileReference.save(). Otherwise, Flash Player throws a runtime error (code 2174). Use FileReference.cancel() to stop an operation in progress. This restriction applies only to Flash Player 10. Previous versions of Flash Player are unaffected by this restriction on simultaneous multiple operations.

Parameters

    Content-Type: multipart/form-data; boundary=AaB03x
    --AaB03x 
    Content-Disposition: form-data; name="Filedata"; filename="example.jpg" 
    Content-Type: application/octet-stream
    ... contents of example.jpg ... 
    --AaB03x-- 
    

See also

Initiate uploading a file to a URL without any encoding. Whereas the upload() method encodes the file in a form-data envelope, the uploadUnencoded() method passes the file contents as-is in the HTTP request body. Use the uploadUnencoded() method if the data you wish to send is already encoded in a format that the receiving server can understand.You typically use the uploadeUnencoded() method with the HTTP/WebDAV PUT method.

Parameters

See also

Dispatched when a file upload or download is canceled through the file-browsing dialog box by the user. Flash Player does not dispatch this event if the user cancels an upload or download through other means (closing the browser or stopping the current application).

This event has the following properties:

package {
    import flash.display.Sprite;
    import flash.events.*;
    import flash.net.FileReference;
    import flash.net.URLRequest;

    public class FileReference_event_cancel extends Sprite {
        private var downloadURL:URLRequest;
        private var fileName:String = "SomeFile.pdf";
        private var file:FileReference;

        public function FileReference_event_cancel() {
            downloadURL = new URLRequest();
            downloadURL.url = "http://www.[yourDomain].com/SomeFile.pdf";
            file = new FileReference();
            file.addEventListener(Event.CANCEL, cancelHandler);
            file.download(downloadURL, fileName);
        }
        private function cancelHandler(event:Event):void {
            trace("cancelHandler: " + event);
        }
    }
}

Dispatched when download is complete or when upload generates an HTTP status code of 200. For file download, this event is dispatched when Flash Player or Adobe AIR finishes downloading the entire file to disk. For file upload, this event is dispatched after the Flash Player or Adobe AIR receives an HTTP status code of 200 from the server receiving the transmission.

This event has the following properties:

package {
    import flash.display.Sprite;
    import flash.events.*;
    import flash.net.FileReference;

            trace("progressHandler name=" + file.name + " bytesLoaded=" + event.bytesLoaded + " bytesTotal=" + event.bytesTotal);
        }

        private function securityErrorHandler(event:SecurityErrorEvent):void {
            trace("securityErrorHandler: " + event);
        }

        private function selectHandler(event:Event):void {
            var file:FileReference = FileReference(event.target);
            trace("selectHandler: name=" + file.name + " URL=" + downloadURL.url);
        }
    }
}

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.

The HTTPStatusEvent.HTTP_RESPONSE_STATUS constant defines the value of the type property of a httpResponseStatus event object.

This event has the following properties:

See also

Dispatched when an upload fails and an HTTP status code is available to describe the failure. The httpStatus event is dispatched, followed by an ioError event.

The httpStatus event is dispatched only for upload failures. For content running in Flash Player this event is not applicable for download failures. If a download fails because of an HTTP error, the error is reported as an I/O error.

This event has the following properties:

See also

Dispatched when the upload or download fails. A file transfer can fail for one of the following reasons:

• An input/output error occurs while the player is reading, writing, or transmitting the file.
• The SWF file tries to upload a file to a server that requires authentication (such as a user name and password). During upload, Flash Player or Adobe AIR does not provide a means for users to enter passwords. If a SWF file tries to upload a file to a server that requires authentication, the upload fails.
• The SWF file tries to download a file from a server that requires authentication, within the stand-alone or external player. During download, the stand-alone and external players do not provide a means for users to enter passwords. If a SWF file in these players tries to download a file from a server that requires authentication, the download fails. File download can succeed only in the ActiveX control, browser plug-in players, and the Adobe AIR runtime.
• The value passed to the url parameter in the upload() method contains an invalid protocol. Valid protocols are HTTP and HTTPS.

Important: Only applications running in a browser — that is, using the browser plug-in or ActiveX control — and content running in Adobe AIR can provide a dialog box to prompt the user to enter a user name and password for authentication, and then only for downloads. For uploads using the plug-in or ActiveX control version of Flash Player, or for upload or download using either the stand-alone or the external player, the file transfer fails.

This event has the following properties:

Dispatched periodically during the file upload or download operation. The progress event is dispatched while Flash Player transmits bytes to a server, and it is periodically dispatched during the transmission, even if the transmission is ultimately not successful. To determine if and when the file transmission is actually successful and complete, listen for the complete event.

In some cases, progress events are not received. For example, when the file being transmitted is very small or the upload or download happens very quickly a progress event might not be dispatched.

File upload progress cannot be determined on Macintosh platforms earlier than OS X 10.3. The progress event is called during the upload operation, but the value of the bytesLoaded property of the progress event is -1, indicating that the progress cannot be determined.

This event has the following properties:

package {
    import flash.display.Sprite;
    import flash.events.*;
    import flash.net.FileReference;
    import flash.net.URLRequest;

    public class FileReference_event_progress extends Sprite {
        private var downloadURL:URLRequest;
        private var fileName:String = "SomeFile.pdf";
        private var file:FileReference;

        public function FileReference_event_progress() {
            downloadURL = new URLRequest();
            downloadURL.url = "http://www.[yourDomain].com/SomeFile.pdf";
            file = new FileReference();
            file.addEventListener(ProgressEvent.PROGRESS, progressHandler);
            file.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
            file.addEventListener(Event.COMPLETE, completeHandler);
            file.download(downloadURL, fileName);
        }

        private function progressHandler(event:ProgressEvent):void {

        }

Dispatched when a call to the FileReference.upload() or FileReference.download() method tries to upload a file to a server or get a file from a server that is outside the caller's security sandbox. The value of the text property that describes the specific error that occurred is normally "securitySandboxError". The calling SWF file may have tried to access a SWF file outside its domain and does not have permission to do so. You can try to remedy this error by using a URL policy file.

In Adobe AIR, these security restrictions do not apply to content in the application security sandbox.

Dispatched when the user selects a file for upload or download from the file-browsing dialog box. (This dialog box opens when you call the FileReference.browse(), FileReferenceList.browse(), or FileReference.download() method.) When the user selects a file and confirms the operation (for example, by clicking OK), the properties of the FileReference object are populated.

For content running in Flash Player or outside of the application security sandbox in the Adobe AIR runtime, the select event acts slightly differently depending on what method invokes it. When the select event is dispatched after a browse() call, Flash Player or the AIR application can read all the FileReference object's properties, because the file selected by the user is on the local file system. When the select event occurs after a download() call, Flash Player or the AIR application can read only the name property, because the file hasn't yet been downloaded to the local file system at the moment the select event is dispatched. When the file is downloaded and the complete event dispatched, Flash Player or the AIR application can read all other properties of the FileReference object.

This event has the following properties:

 
package {
    import flash.display.Sprite;
    import flash.events.*;
    import flash.net.FileReference;
    import flash.net.URLRequest;

Dispatched after data is received from the server after a successful upload. This event is not dispatched if data is not returned from the server.

This event has the following properties:

Note: To run this example, change the uploadURL.url property to point to an actual URL, rather than the fictional one in the example. The URL should point to a file named yourUploadHandlerScript.cfm in the root web directory of the URL specified. Based on your configuration, you might also need to compile the SWF file with Local Playback Security set to Access Network Only or to update Flash Player security settings to allow this file network access.
