# Knowledge Management

The character system supports two knowledge modes:

#### Classic Mode (Default)[​](https://elizaos.github.io/eliza/docs/core/characterfile#classic-mode-default) <a href="#classic-mode-default" id="classic-mode-default"></a>

* Direct string knowledge added to character's context
* No chunking or semantic search
* Enabled by default (`settings.ragKnowledge: false`)
* Only processes string knowledge entries
* Simpler but less sophisticated

#### RAG Mode[​](https://elizaos.github.io/eliza/docs/core/characterfile#rag-mode) <a href="#rag-mode" id="rag-mode"></a>

* Advanced knowledge processing with semantic search
* Chunks content and uses embeddings
* Must be explicitly enabled (`settings.ragKnowledge: true`)
* Supports three knowledge types:
  1. Direct string knowledge
  2. Single file references: `{ "path": "path/to/file.md", "shared": false }`
  3. Directory references: `{ "directory": "knowledge/dir", "shared": false }`
* Supported file types: .md, .txt, .pdf
* Optional `shared` flag for knowledge reuse across characters

#### Knowledge Path Configuration[​](https://elizaos.github.io/eliza/docs/core/characterfile#knowledge-path-configuration) <a href="#knowledge-path-configuration" id="knowledge-path-configuration"></a>

* Knowledge files are relative to the `characters/knowledge` directory
* Paths should not contain `../` (sanitized for security)
* Both shared and private knowledge supported
* Files automatically reloaded if content changes

**Knowledge Tips**

* Focus on relevant information
* Organize in digestible chunks
* Update regularly to maintain relevance
