# Generated files

> Find, preview, download, reuse, or delete the private files Mythos generates for a project.

The **Files** tab holds downloadable files Mythos creates for you. These are private project
deliverables, separate from the pages and assets used by your published site.

Ask for the result you need in plain language. Mythos can create documents, spreadsheets, data
exports, charts, images, videos, archives, and other supported outputs. Available output types may
change over time, so this page does not treat the examples as a closed list.

## Generate a file

#### Describe the deliverable

In chat, name the content, purpose, and preferred file type. Include the
data or constraints the result must follow.

#### Send the request

Mythos creates the file as part of the request. When delivery succeeds, the
new output appears in the project's **Files** tab.

#### Review the result

Open **Files**, search by filename, and select the output. Mythos shows an
in-browser preview when that file type supports one.

#### Use the file

Select **Download** to save a copy, or **Reference in chat** to include a
supported generated file in a later Build request. You can reference up to three generated files
in one request.

Example requests:

```text
Create an editable project brief from the requirements above.
```

```text
Export these orders as a spreadsheet with date, customer, item, and total columns.
```

```text
Make a bar chart that compares monthly signups and include a downloadable image.
```

## Manage generated files

The Files view groups outputs by type and includes search. Select a file to preview it, download it,
reference it in chat, or delete it. Switch between list and grid views to find the result you need.
Review the file before using it: check the data, formatting, and any facts or calculations.

If a later request produces a file with the same name, it replaces the earlier file instead of adding
another copy. Download an earlier result before asking for a same-name replacement if you need to
keep both.

Most generated files can be up to **25 MiB**; generated videos have a **20 MiB** limit. Files keeps
the newest **100** generated files for each project.

## Generated files vs project files

* A generated file in **Files** is a private deliverable. It does not automatically appear on the
  website or become public when you publish.
* Website images, styles, and other app assets belong to the project itself and appear in **Code**.
* Files attached to a prompt are inputs for that request. They do not appear in **Files**; see
  [Chat attachments](/features/chat-attachments).

To place a generated image, chart, or document on the site, reference it in a new prompt and clearly
ask Mythos to add it to the page.

## Troubleshooting

#### The file is not in Files

Confirm that the request completed successfully, then refresh the Files
view. An unfinished or failed delivery does not add the output.

#### Preview is not available

Some file types are download-only. Select **Download** and open the file in
an app that supports it.

#### I cannot find an older file

A same-name output may have replaced it, or it may have aged out after the
project reached 100 generated files.
