Most files open right in Drime: you can look at them without downloading anything.

## Open a preview

Double-click the file. You can also right-click it and choose **Preview**, or select it and press `Ctrl` + `Alt` + `P` (`Cmd` + `Option` + `P` on a Mac).

The list of formats Drime can show is in [File types you can preview in Drime](https://drime.cloud/support/drive/supported-file-types). Files Drime cannot preview can still be stored and downloaded.

## Comment on a preview

In the preview, you can comment on the file, and pin a comment to an area of an image. See [Comment on files and mention people](https://drime.cloud/support/sharing-and-collaboration/comments-and-mentions).

## Watch a video

The video player lets you:

- change the speed, from 0.5x to 2x;
- loop the video, jump 10 seconds back or forward, or move frame by frame;
- go full screen with `F`;
- use the current image as the video's thumbnail with **Set this frame as a thumbnail**.

You can also add subtitles: see [Watch videos and add subtitles](https://drime.cloud/support/drive/watch-videos-and-add-subtitles).

If your browser cannot play the video's format, Drime offers **Convert in this browser**.
