Abstract: Examples disclosed herein relate to a hierarchical file system. The hierarchical file system may include a first and a second virtual file referencing a stored data set. The first virtual file may include a set of first keys of a first level of specificity, with each key of the set of first keys including a record locator. The second virtual file may include a set of second keys referencing the data set and of a second level of specificity. The set of first keys within the first virtual file is searched in response to a query for data of the data set. A key from the set of second keys is accessed via the record locator from a key from the set of first keys where the data of the data set was not identified by the set of first keys.
