删除文件就是这么简单

var f = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, 'delete_me.txt');
f.write('foo');
// make sure there's content there so we're sure the file exists
// Before deleting, maybe we could confirm the file exists and is writable
// but we don't really need to as deleteFile() would just return false if it failed
if (f.exists() && f.writeable) {
    var success = f.deleteFile();
    Ti.API.info((success == true) ? 'success' : 'fail'); // outputs 'success'
}
