Files cannot be stored directly on the ethereum blockchain, as it would be too costly. We need to find a way to store files such that they will always be accessible forever at a static address. Also, we need to be able to verify that the file has not changed.
Through hashing the file, we can verify that the file has not changed. We can then use that hash as the static address. However we still need to find a place to store the file so that it will always be accessible.
