# Files

How ENERCALC stores your projects and calculations, and why there is no project file for you to manage.

## There is no project file to manage

ENERCALC looks after your work for you. Your projects, their divisions, and every calculation inside them are saved through the ENERCALC API and held in our infrastructure.

There is no project file sitting on your computer, which means there is nothing for you to name, nothing to move into the right folder, and nothing to remember to copy before you switch machines. Because your work lives in our infrastructure rather than on a disk, it is not tied to the computer you created it on.

{% hint style="info" %}
**NOTE:** This is true whether you use the web version at <https://enercalc.app/> or an installed Windows or Mac build. They all work against the same projects.
{% endhint %}

If you are arriving with work from elsewhere, the **Projects** tab can import a project from a `json` or `ec6` file, and export one back out to `json`. See [Projects Tab](/docs/onboarding/program-overview/interface-navigation/project-assistant.md).

## Saving your work

You save a calculation from inside the calculation itself, not from the main menu. Once a calculation is saved, it belongs to the project you are working in and is available the next time you open that project.

## What the Project Manager is showing you

The Project Manager shows the divisions and calculations that make up the project you have open. It is a view of your project, not a view of a folder on a disk, so moving things around in it does not move anything on your computer.

## Databases

ENERCALC supplies the section and material databases that the calculation modules draw on, including rolled steel sections, wood sections, and wood reference design values. These are maintained for you rather than installed as files you look after.

For what each database contains, see [Databases](https://enercalc.com/docs/user-manual/main-menu/databases-in-main-menu) in the User Manual.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://enercalc.com/docs/onboarding/program-overview/interface-navigation/files-file-locations.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
