Use cases seperated in time

Hi

We currently have a lot of use cases in our model and want to decrease the number.

We have two use cases: archive files and view archived files. Archive files happen once a week on old files, a clock initiates this use case and is thus the actor. View archive files is initiated by a user any time during the week.

Is there a way to merge these two use cases, and how would your approach be?

We really want to decrease the number of use cases, and archive files is a very small use case.
