->  This example creates a new file, if the file does not already exist. If an application must create a file, that application must `Create` permission for the folder. Permissions are set by using access control lists. If the file already exists, the application needs only `Write` permission, a lesser permission. Where possible, it is more secure to create the file during deployment, and only grant `Read` permissions to a single file (instead of Create permissions for a folder). Also, it is more secure to write data to user folders than to the root folder or the Program Files folder.
