From RL Consulting:
Extreme Fast Data Organizer (ExFDO) is a powerful organizer implementing a fast organization method to quickly store and find your personal data and objects without losing time to search everywhere and to create organization schemes that can be forgotten or changed. This method is based on the principle that "Data and Physical objects are subjects". So, each time you deal with a subject, whatever is the subject, create it and add data to it using ExFDO. Added data can be files, notes, URLs, secret data, location of objects, tasks to do, search keywords. In this way, you constitute as you go along, a big database of personal subjects that you can easily query to quickly find what you look for whether it is computer files, notes, URLs, passwords, paper documents, data storage Medias, or any personal data or object. The software is portable and very efficient if installed on a dedicated External Hard Disk (USB) which is used to host all your personal subjects and data for life. Here is some features of ExFDO :
Creating and organizing subjects.
Adding and updating subjects data (files, notes, urls, secret data, locations of objects, tasks to do, keywords).
Cataloguing folders and files from any directory or drive as subjects.
