The AllMyNotes Organizer is a personal information management application for Windows. It provides a note-taking tool. Then you can arrange your notes (plus quotations, links, contact information, and more or less anything else you might want to record in a text file) in a customisable, easily searchable hierarchical folder structure.
Desktop and portable versions are available – the latter allows you to keep the program on a USB stick or similar, for use on multiple PCs without the need to install anything.
A basic version of the AllMyNotes Organizer is free of charge. The Deluxe Edition, which costs about £20, offers additional features, such as colour coding, alarms and reminders, and the option of password protection.
