I have a string the user has typed and I want to save it into a file on the users harddrive. Can you do that? And if so, how?

Yes you can, with FileReference. This is basically how it's done:
var bytes:ByteArray = new ByteArray();
var fileRef:FileReference=new FileReference();
fileRef.save("fileContent", "fileName");
Doesn't look too hard, does it? And here's a video-tutorial on it too:

And the documentation:

Hope that helps.

What is the purpose of
var bytes in the example?Since I had a function to output bytes to a file (because I was doing something with bitmaps), I reused it to output a string as well, like this:
var filename:String = "/Users/me/path/to/file.txt";
var byteArray:ByteArray = new ByteArray();
byteArray.writeUTFBytes(someString);
outFile(filename, byteArray);
private static function outFile(fileName:String, data:ByteArray):void {
var outFile:File = File.desktopDirectory; // dest folder is desktop
outFile = outFile.resolvePath(fileName); // name of file to write
var outStream:FileStream = new FileStream();
// open output file stream in WRITE mode
outStream.open(outFile, FileMode.WRITE);
// write out the file
outStream.writeBytes(data, 0, data.length);
// close it
outStream.close();
}

In addition, you must have Flash Player 10 and a Flex Gumbo SDK installed in your Flex Builder 3.
You can also have a look the following example: http://blog.flexexamples.com/2008/08/25/saving-files-locally-using-the-filereference-classs-save-method-in-flash-player-10/

the link provided is a dead link
In Flex 3 no you can't do it unless you upload the file to the server and then download the file via a url to the desktop.
In Air or Flex 4 you can save it directly from the application to the desktop as detailed above.
