What are .thm and .lrv files?

When I go to download video from my GoPro’s memory card, there are some other files on there in addition to the MP4 video file. They have the same filename but a different extension (LRV and THM).

Are these important? Can I delete them?

Hi @lomulomu

Depending on what camera you are using, what software version you have installed, and what resolution you are recording video in, you may notice .thm and .lrv files stored on your camera after recording video.

  1. .thm files are Thumbnail video files which are used to display a thumbnail image of the video
  2. .lrv files are Low Resolution Video files. These will be created if:

These files are necessary to support the Copy, Playback, and Share functionality in the latest version of the GoPro App.

This article provides a lot more info, should you need it.
