Ooniki mentioned some problems with mail databases on server světNotes.cz. He has a problem with databases which are quite big and Lotus Notes reports that they usage is high but, in fact, there is just few documents and when you force compact on them they gets smaller a lot. Well, I decided to write a small tool to detect these databases. It goes across specific databases, count its documents and their sizes and report these numbers across year/quarters/months. On this basis you can decide how to setup archiving criteria or which databases are really strange.
More details how to use it is in Usage document of this database, so check it and be happy.
