Archmbox lets you list, move, and copy messages from one mbox mail file to another, primarily for archiving messages. This tool lets you easily move all messages that are older than a given date into another (possibly compressed) mbox file, and you can also grab or delete messages by matching regular expressions against message headers.

Although Microsoft publicly testifies from every available pulpit of their deep longing for multiple document formats, a quick glance at reality shows that this love remains unrequited in their products. For example, what new formats does Office 2007 include out of the box?

As I already explained in another article file formats are extremely important: unless, at least in Public Administrations (PAs), only open file formats are used, serious amounts of public money can go to waste, important public digital documents may become unreadable and private citizens or businesses may be forced to useless expenses if they want to interact with PAs.
