fs.position = 5;
fs.writeUTFBytes(".yuhang");
fs.close();
|
（2）下面例子將內容添加到文件末尾
| 1 2 3 4 5 |

fs.close();
|
3，讀取文件內容

var str:String = fs.readUTFBytes(fs.bytesAvailable);fs.close();
|
4，移動文件
| 1 2 3 |
var originalFile:File = File.documentsDirectory.resolvePath("hangge.txt");
var newDir:File = File.applicationStorageDirectory.resolvePath("hangge.txt");
originalFile.moveTo(newDir);
|
5，復制文件
| 1 2 3 |
var originalFile:File = File.documentsDirectory.resolvePath("hangge.txt");
var newDir:File = File.applicationStorageDirectory.resolvePath("hangge.txt");
originalFile.copyTo(newDir);
|
6，刪除文件
| 1 2 3 4 |
var fileObj:File = File.documentsDirectory.resolvePath("hangge.txt");
if(fileObj.exists){
fileObj.deleteFile();
}

7，創建文件夾
| 1 2 |
var fileDir:File = File.documentsDirectory.resolvePath("hangge");
fileDir.createDirectory();
|
8，移動文件夾

var originalDir:File = File.documentsDirectory.resolvePath("hangge");
var newDir:File = File.applicationStorageDirectory.resolvePath("hangge");
originalDir.moveTo(newDir);
|
9，復制文件夾
