Ask HN: Anyone else use a single gigantic .txt file as a notetaking solution?

4•superconduct123•9mo ago
For the last 3 years I've just been using notepad in windows and a single .txt file to keep notes for my programming job.

Every day I just open the file and add a new divider for the day at the top of the file like this:

May 13, 2025

------------------------

After 3 years I'm at 25,000 lines, 700KB in size

* Its super fast and lightweight

* notepad opens instantly

* notepad takes up very little screen space

* searching is still instant with CTRL + F

* Want to tag something? Just write "tag:something" and search for that later

It sounds kind of stupid at first, like how do you quickly get to old notes?

But I've realized over time I generally only care about the last week or 2 of notes and rarely reference older ones.

I'm curious if anyone else does this and what your stats are for the file and if you ran into any issues

I used to do this and it worked pretty well I thought.

I eventually broke it into years (YYYY-MM-DD-notes.txt and just grep'd the directory.

Finally I made it to markdown files also stored in the same directory.

It was great for searching.

I use markdown in an IDE (vscode). It’s very nice. You get: some formatting, auto indentation, indentation, identifier search (jump to heading with fuzzy search), code highlighting, etc.

Aren’t you worried about a single point of failure if you keep everything in 1 file?
OhMeadhbh•9mo ago
yes. though i have a bunch of large files, one per project. but grep works on one file as easy as several, so i've started doing a week per file in a per-project directory.
