Question

是否可以使用暂停/恢复功能？

source.copyTo（destination）;

如果你最早能发送它会很棒。

Answer 1

我在这里找到了一个解决方案CookBook from Adobe

private function copyInto(directoryToCopy:File, locationCopyingTo:File):void
{
    var directory:Array = directoryToCopy.getDirectoryListing();

    for each (var f:File in directory)
    {
        if (f.isDirectory)
          copyInto(f, locationCopyingTo.resolvePath(f.name));
        else
          f.copyTo(locationCopyingTo.resolvePath(f.name), true);
    }
}

Answer 2

或者你可以使用File.copyTo（）方法：

var source:File = new File();
source.resolvePath( 'sourceFolder' );
var destination:File = new File();
destination.resolvePath( 'destinationFolder' );
source.copyTo( destination );

如果目录很大并且您不希望应用程序卡在等待副本，则可以使用copyToAsync，这将导致源文件在作业完成时调度Event.COMPLETE。

如果有人想复制整个目录，这是上面修改过的代码;空文件夹和所有。注意参数中使用的“copyEmptyFolders”参数。

    //Recursivley copies directory.
    private static function copyInto(directoryToCopy:File, locationCopyingTo:File, copyEmptyFolders:Boolean=true):void
    {

        var directory:Array = directoryToCopy.getDirectoryListing();

        for each (var f:File in directory)
        {
            if (f.isDirectory)
            {

                // Copies a folder whether it is empty or not.
                if( copyEmptyFolders ) f.copyTo(locationCopyingTo.resolvePath(f.name), true);

                // Recurse thru folder.
                copyInto(f, locationCopyingTo.resolvePath(f.name));

            }
            else
                f.copyTo(locationCopyingTo.resolvePath(f.name), true);

        }

    }
