# Organize digital notes so your study library stays useful

> Digital notes become another pile when every capture lands in one list or every idea gets its own complicated category. In BrainDen, use nested folders for stable course and topic structure, links for relationships that cross those folders, and a short maintenance routine that keeps mixed PDFs, recordings, images, videos, and text easy to retrieve.

## What this workflow gives you

### Let folders answer where

Use folders for stable context such as semester, course, module, or research project so a note has one predictable home.

### Let links answer how ideas relate

Connect a note to a prerequisite, supporting example, contrasting argument, or later application even when the notes live in different folders.

### Keep source and study output together

Retain the PDF, recording, transcript, image, or video connection so a concise note never becomes detached from the material you may need to verify.

## Build a folder-and-link system you can retrieve

1. **Choose the smallest stable hierarchy:** Start with the broad context you repeatedly use, then add only levels that help retrieval. A semester, course, and topic is often enough for class material.
2. **File notes by subject, not file type:** Keep the lecture recording, reading, image, and explanation for one topic near each other instead of building separate top-level folders for every input format.
3. **Connect and review the library:** Add links where relationships matter, inspect backlinks when revisiting a core concept, and select several notes for one focused review rather than opening every note in the folder.

## Example: a mixed digital economics library

**Input:** A semester of lecture recordings, PDF readings, photographed whiteboards, tutorial notes, and revision summaries across microeconomics and macroeconomics.

**Possible output:**

- A semester folder with course and topic subfolders rather than separate audio, PDF, and image silos
- Links from an elasticity note to the relevant lecture, worked example, and consumer-choice reading
- A selected exam-topic set that can be read continuously while every source note stays in its original home

## How to get a better result

### Use names you will search for

Put the recognizable concept, course code, week, or question in the title. Avoid decorative naming systems that require you to remember hidden rules under exam pressure.

### Avoid folders with only one possible note

Create another level when several items genuinely share it. A shallow hierarchy with meaningful links is easier to maintain than many nearly empty folders.

### Run a short weekly reset

File loose notes, correct unclear titles, add important links, and mark missing topics. The routine should repair retrieval problems rather than reorganize the whole library.

## Frequently asked questions

### What is the best folder structure for digital study notes?

Use stable levels that match how you learn, such as semester, course, and topic. Add module, week, lab, or project levels only when they make material easier to find.

### Should I organize notes by subject or by file type?

For study, subject and topic usually provide better retrieval. Keep a topic's PDF, recording, image, and typed notes in the same context while each source remains attached.

### When should I link notes instead of moving them?

Keep the note in its primary course or project folder and link it when the same idea supports another topic, provides evidence, or explains a prerequisite.

### Can I review notes from different folders together?

Yes. Select the notes needed for one topic, read them continuously, and export the selection as one PDF or Markdown document without changing the originals.
