HDF

HDF, or Hierarchical Data Format, is a file format and set of tools used for storing, organizing, and sharing large amounts of scientific data. It allows different types of data—like images, tables, and metadata—to be stored in a single file in a structured way. This format is particularly useful in fields like science and engineering, where complex datasets need to be efficiently managed and accessed. HDF supports data compression and can handle very large datasets, making it a popular choice for researchers and institutions dealing with extensive information.
