- Midas Blue Files:
  - The Midas Blue File is the standard binary file format used by modern Midas frameworks.
    - Blue files are so ubiquitous in Midas applications that many people erroneously refer to a Blue file as simply a "Midas File".
    - Blue files are designed to efficiently store one-dimensional or two-dimensional signal data as well as record-based information.
- History:
  - The Blue file format was preceded by the Gold file format.
    - Gold files have not been used for several years now.
    - These days when people talk about a "gold file" this is in reference to a standard or "gold copy" of a file and not a file in the Gold file format.
  - The design of Blue files grew out of the Midas community over several decades.
    - The definition of the Blue file format was officially codified in 2006.
    - See Midas BLUE File Format / Version 1.2.0 (CCD-2006002-1.2.0).
- Extensions:
  - Typically Blue Files use either a `.prm` or a `.tmp` extension.
    - The original intent was for `.prm` files to be "permanent" and `.tmp` files to be "temporary," but this is rarely followed.
    - If a file is specified without an extension, most Midas frameworks will automatically add either a `.prm` or a `.tmp` extension on. (This has led to confusion and it is best to avoid this "feature.")
