Question

How to put\save files into your application directory? (adobe air) (code example, please)

Answer 1

@glendon if you try to save directly to applicationDirectory it will indeed throw an error, but it seems you can move the file in the filesystem. i used the code below after yours:

var sourceFile:File = File.applicationStorageDirectory.resolvePath ("file.txt");
var pathToFile:String = File.applicationDirectory.resolvePath ('file.txt').nativePath;
var destination:File = new File (pathToFile);
sourceFile.moveTo (destination, true);

the reason why you 'shouldnt' use the application folder is because not all users have rights to save files in such folder, while everyone will in applicationStorageDirectory.

Answer 2

It's not recomended but it is possible. Construct your File reference like this:

var pathToFile:String = File.applicationDirectory.resolvePath('file.txt').nativePath;
var someFile:File = new File(pathToFile);

Answer 3

You can't write to your AIR app's Application Directory, it's not allowed. You can however write to a folder that your AIR app creates in the user's directory, called the Application Storage Directory. If you need config files and the like, that's probably the best place to put them. See 'applicationDirectory' in the docs link below:

Answer 4

The accepted answer works!

But if I do this instead:

var vFile = File.applicationDirectory.resolvePath('file.txt');
var vStream = new FileStream();
vStream.open(vFile, FileMode.WRITE);
vStream.writeUTFBytes("Hello World");
vStream.close();

It will give SecurityError: fileWriteResource. However, if I use applicationStorageDirectory instead, the above code will work. It'll only NOT work if it's applicationDirectory. Moreover, Adobe's documentation also says that an AIR app cannot write to its applicationDirectory.

Now, I wonder if it's a bug on Adobe's part that they allow writing to the applicationDirectory using the way suggested by the accepted answer.
