title: Ways of Efficiently Seeking in Custom File Formats
body: <p>I've been wondering what kind of ways seek is implemented across different file formats and what would be a good way to construct a file that has a lot of data to enable efficient seeking. Some ways I've considered have been having equal sized packets, which allows quick skipping since you know what each data chunk is like, also preindexing whenever a file is loaded is also a thought.</p>
