# 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.
