Demonstrates basic filesystem CRUD operations with Titanium

filesystem_example.js

var dataToWrite = {"en_us":{"foo":"bar"}};

//NOTE: remember to use applicationDataDirectory for writes
var newDir = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory,'mydir');
newDir.createDirectory();
Ti.API.info('Path to newdir: ' + newDir.nativePath);

var newFile = Titanium.Filesystem.getFile(newDir.nativePath,'newfile.json');

//Stringify the JavaScript object we created earlier and write it out to the new file
newFile.write(JSON.stringify(dataToWrite));

var newFile = Titanium.Filesystem.getFile(newDir.nativePath,'newfile.json');
var resources = JSON.parse(newFile.read().text);

resources.en_us.foo = 'baz'; //bar becomes baz
newFile.write(JSON.stringify(resources));

//We already have references to the file and directory objects.
//We just need to call their cooresponding delete methods.
newFile.deleteFile();
newDir.deleteDirectory();
