Archivarius 3000

According to their website:

Archivarius 3000 is a full-featured application to search documents and e-mail on the desktop computer, your local network and removable drives (CD, DVD). The documents can be searched by content, the same as with Internet search engines.

There are colleagues who do not use full-text search applications on principles. Others are just may not be aware of how useful they are. Given its price and capabilities, I wholeheartedly recommend Archivarius 3000 to both.
