Skwyrul - personal information manager (pronounced "squirrel")
I use an older freeware PIM at work and I'm planning on switching to this one. It's got the main features I need and a few extras as well.

Skwyrul PRO v4.0a is a powerful information manager that allows you to store and manipulate data in many different ways. It is based upon a tree storage idea, but goes much further.
Multiple concurrent file access
