QuickNote is a .txt and .rtf note editor and organiser. It does not use a database; instead, notes are saved as separate files. So one can access them with windows explorer. It shows all the subfolders under the working directory as nodes and subnodes in a tree-view pane. Files under the selected folder are shown in the second pane. From there, one can open a file by double-clicking in the third pane. It supports multiple tabs.
