## Capabilities

### Build a real hierarchy

Create a semester folder, add courses inside it, then organize each course by module, week, or topic.

### Move notes where they belong

Keep new and existing notes inside the folder that makes sense as your study system changes.

### Share a folder's notes

When needed, share the notes directly inside a folder as one public collection.

## How it works

1. **Start with the broadest level:** Create a semester, qualification, or major project folder.
2. **Add course and topic folders:** Match the hierarchy used by your syllabus or learning goal.
3. **File notes as you create them:** Keep every new source and note in the right context from the start.

## Frequently asked questions

### Can BrainDen create folders inside other folders?

Yes. Nested folders let you represent structures such as semester, course, module, week, and lecture.

### Can I share a folder rather than every note separately?

### Do links between notes still work across folders?

Yes. Notes can be linked across the library, and backlinks make those relationships visible from either note.
