The information in this article applies to all paid Dropbox users.
All files supported by your device preview in the Dropbox app. For other types of files, the app will automatically search your device for an application that can open the file type you’re attempting to preview. If Dropbox can't find an application capable of viewing your file type, you'll need to install an app that can open your file in order to preview it.
See a list of file types that preview on dropbox.com.
