I have published a simple FileWriter API for Adobe Apollo which is essentially an all static class providing methods for synchronous and asynchronous File creation.

FileWriter encapsulates file creation in an all static class which can be used to easily and intuitively create files to a local file system simply by specifying the name of the file to create as well as the path in which to the file is to be created.

FileWriter will create a new file if the file does not currently exist and return an open FileStream referencing the file object via FileMode.WRITE, otherwise FileWriter will open a previously created file and return an open FileStream referencing the File via FileMode.UPDATE.

You can view the source as well as download the basic sample application which allows you to create a File to your desktop utilizing the FileWriter API.
