# Introduction

The AddContentFileToProject method can be called to add an existing file to the project. The file must already be located relative to the main project's content folder. For XNA applications this means relative to the folder that contains the .contentproj file. Non-XNA projects usually have a Content folder relative to the .csproj (or .vcproj) file. If so, the file should be located in this location. This simply adds a code file to the Visual Studio project - it does not add it to Glue, nor does it perform any code generation. The absolute file name must be passed to the method.

## 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://docs.flatredball.com/flatredball/api/glue-plugin-api/flatredball-glue/plugins/flatredball-glue-exportedinterfaces-iprojectcommands-addcontentfiletoproject.md?ask=<question>&goal=<endgoal>
```

`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.
