# Renaming MTS files

1. If you haven't already done so, copy the media files on your device (Canon video camera, iPhone, Zoom H2n, etc.) into your project folder. 
2. Disconnect the device and [navigate](https://app.gitbook.com/@techresources/s/file-and-folder-management-windows/navigating-folder-tree) to the media files in your project folder. **Note**: To navigate to media files from a Canon video camera, you'll need to do the following:
   * Double-click your renamed **AVCHD** folder (see [Copying media files from a Canon video camera](/adobe-premiere-basics-windows-edition/setting-up-your-project/adding-media-from-a-video-camera.md) if you haven't renamed this folder.)
   * In your renamed **AVCHD** folder, you'll see two folders (**BDMV** and **Canon**.) Double-click the **BDMV** folder.
   * In the **BDMV** folder, you'll see several folders. Double-click **STREAM**. The files  in this folder are your media files (00000.MTS, etc.)
3. Rename all of the MTS files in the **STREAM** folder. Do this by adding a letter to the end of the default filename (for example, 0000.MTS becomes 0000a.MTS.) Use the same letter for all of the MTS files (see image below.) Do not use a letter used in a previous project. **Note**: Be sure to maintain the .MTS extension at the end of the filename.

## 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://techresources.gitbook.io/adobe-premiere-basics-windows-edition/setting-up-your-project/previewing-and-renaming-clips-in-finder.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.
