# The Backpack
## What Is the Backpack
The **Backpack** allows you to store and transfer blocks across different questions or courses. By dragging blocks into the backpack within the rules editor of the Dynamic Engine, you can easily save and reuse useful code snippets or frequently used blocks. This helps streamline question building.
The backpack is an icon in the top right of the Dynamic Engine. It looks like this:
## How It Works
To use the backpack, follow these simple steps:
1. **Drag Blocks to Backpack**: Click and hold the block you wish to store, then drag it into the backpack icon located on the interface.
2. **Store Your Blocks**: Release the mouse button to drop the block into the backpack. The backpack can hold multiple blocks and is useful for transferring snippets across projects.
3. **Retrieve from Backpack**: To use a block from the backpack, click on the backpack icon, then drag the block from the backpack onto the workspace.
4. **Manage Backpack Content**: You can clear the backpack or individually remove blocks as needed, ensuring you keep only the most relevant blocks at your fingertips.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://examind.gitbook.io/v1/examind-platform/build/question-builder/dynamic-questions/dynamic-engine/the-backpack.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
