For our advanced users
Special considerations for text files:
- .htm and .html files do not preview in public links shared via the public folder
Special considerations for image and video files:
- For .psd files, we recommend saving your files with the preference to maximize compatibility.
- Video codec created via GoToMeeting can be previewed.
- When you save a video in your Dropbox you will be able to watch the full video from a preview page.
- If a Dropbox Business user creates a shared link to a video, the recipient can view the entire video on a preview page. This does not apply to videos created by users on a Dropbox Business trial.
- If a Dropbox Basic, Pro, or Business trial user creates a shared link to a video, the recipient can only view up to 15 minutes on a preview page. Recipients can download the file to their computer or add it to their own Dropbox account to view the entire video.
