n. ~ A collection of documents (a file) relating to a particular investigation or in support of some administrative action.
Case files are sometimes referred to as a project file or, in Canada, a transactional file. Also called dossiers, although that term has a more general sense of file. Case files are often found in the context of social services agencies (public and private), and in Congressional papers. Examples include criminal investigations, patient records, and tenure files. The types of documents in each file in a series of case files tends to capture the same categories of information about each case.
