I’m using IMI organzier for years to manage filing of all my downloads.

A PRO edition is just launching:

IMI Organizer PRO Edition
Additional Features:
- Provides Project-Related Folders with the ability to create new projects and generate a new mind-map that points to those new project folders.
- Provides Content Management Tools to speed up the organization of content that users have already downloaded.
- Provides the ability to create DAO Installers (see below: DAO = Download and Automatically Organize)
