First, I'd make sure you update your Flex Builder to the latest version (Flex Builder 3.0.2 with Flex SDK 3.2). For instructions, check out <a href="http://blog.flexexamples.com/2008/11/19/upgrading-to-flex-builder-302/" rel="nofollow"><u>"Upgrading to Flex Builder 3.0.2"</u></a>. This ensures you're using the latest version of Flex Builder and the latest stable version of the Flex SDK (although you are able to download nightly builds of the Flex SDK which may include additional bug fixes). For more information, see <a href="http://blog.flexexamples.com/2008/08/01/downloading-and-installing-flex-sdk-builds-from-opensourceadobecom/" rel="nofollow"><u>"Downloading and installing Flex SDK builds from opensource.adobe.com"</u></a> and <a href="http://blog.flexexamples.com/2008/08/02/using-the-beta-gumbo-sdk-in-flex-builder-3/" rel="nofollow"><u>"Using the beta Gumbo SDK in Flex Builder 3"</u></a>. But, back to your question. Check out the FileReference archive on this site at: <a href="http://blog.flexexamples.com/tag/filereference/" rel="nofollow"><u>http://blog.flexexamples.com/tag/filereference/</u></a>. Or more specifically, check out the following article: <a href="http://blog.flexexamples.com/2008/08/25/previewing-an-image-before-uploading-it-using-the-filereference-class-in-flash-player-10/" rel="nofollow"><u>"Previewing an image before uploading it using the FileReference class in Flash Player 10"</u></a>. I'm not sure if the latest version of Flash Player 9 has similar capabilities, but the previous solution was that after the user selected a file from their OS, you would need to upload the file to a server-side script and then download the file back to the client using FileReference again, and then you could parse the XML document and display it in a DataGrid or whatever. Personally, I think the easiest solution would be to use Flash Player 10 and following the <a href="http://blog.flexexamples.com/2008/08/25/previewing-an-image-before-uploading-it-using-the-filereference-class-in-flash-player-10/" rel="nofollow"><u>"Previewing an image before uploading it using the FileReference class in Flash Player 10"</u></a> entry. Next, in the <code>fileReference_complete()</code> method I'd convert the <code>fileReference.data</code> property to an XML object and then set the DataGrid control's data provider to an XMLList or XMLListCollection object. You may need to use some label functions to display the XML data correctly, but it should be fairly easy. The trickier part is that the user could select any file or the wrong type of XML document structure, so you may need to add some clever validation to ensure the XML data is what you expect. Happy Flexing! Peter Dave,

I used it in one of my applications for creating a flex downloader. This downloader fetches a list of files to be downloaded from the server. Once the list is retrived, on clicking the file names in the list it will open a save dialog box and start downloading the file. My concern is that, I need to create a downloader where in the destination folder is selected by the user for saving the files and then one by one the files are to be downloaded to that folder. Can any one show me some way to do it in Flex? Thanks for any help saji Hi Thanks for this great example. I used it in one of my applications for creating a flex downloader.

Actually, the problem is that i defined my FileReference Object in the same function that i call the download() method. A quick workaround is to declare a dummy function or define your FileReference object outside the function.
