Why? It seems to me that reading entire file to calculate its hashes is a waste of time compared to just reading the entire file. Calculating hashes is useful in two circumstances: 1) When comparing one document to many (or many to many), 2) When a compact signature of the file is needed (for ease of communication or storage).
