Hierarchical Data Format

Hierarchical Data Format (HDF) is a way to organize complex data in a structured, folder-like system within a single file. It allows storing different types of related data—such as images, measurements, or tables—together, with each set organized in nested groups or categories. This structure makes it easier to access, manage, and share large and diverse datasets efficiently. Think of it like a well-organized digital filing cabinet, where everything is stored in folders and subfolders for quick retrieval and clarity.
