Tree-structured text editor / note-taker

Question

Looking for a tree-structured hierarchical text editor / note-taker.

Requirements:

1. Freeware
2. Not ancientware (must have been updated during the last 3 years)
3. Support italics/bold text
4. Windows 7 SP1 compatible
5. Can successfully import Treepad Lite files

Cherrytree seems to be an obvious contender, but the memory footprint of it in Windows seems extremely large.

Answer 1

You may try:

• Wunderlist (note-taker for mobile and desktop)
• KeyNote [code] (it supports tree style editing),
• Evernote (notebooks and tags which can be tree organised),
• TreeSheets (it's table based),
• The Guide (file format is human readable like XML),
• wikidPad (wiki-like editor),
• Zim (notes are saved as text files in folder hierarchies),
• Treepad Lite,
• 2do (Notes management),
• Things (task management for Mac & iOS),

Answer 2

Treeline

Treeline is a very nice cross-platform (Win 7, 8; Linux) hierarchical notes manager. It is similar to Treepad (as the author himself notes).

As for OP's requirements:

1. Freeware
2. Not ancientware (must have been updated during the last 3 years)
3. Support italics/bold text | and more besides
4. Windows 7 SP1 compatible
5. Can successfully import Treepad Lite files | Not sure - Treeline can import "plain text, tab-indented text and tab-delimited table files" as well as "generic XML files" (and import/export its own HTML); Treepad Lite can export (according to the online documentation) HTML and a "Treepad Lite file". There might be something compatible in there, but I'm not sure.

It ticks enough boxes to be worth investigation, at any rate. I use it from time to time under Ubuntu and enjoy having it in the "toolkit".

Answer 3

I like Workflowy It's web based, works on mobile and offline too. You can share bullets.

Meets most requirements:

1. Freemium. Free gets 500 new bullets/month, no password protected sharing, no auto-backup to Dropbox.
2. Stable, under active development
3. Supports italics/bold text
4. Web based, so supports all OSes with modern browsers
5. You might be able to simply paste your old data to import it.

Answer 4

Online notepad on the web for all devices with flexible tree-like structure.

Currently not supported:
