OneDrive's vision is to enable you to share and work together on all your files in a simple and secure way, inclusive of your personal files as well as the files you create and manage in shared spaces like SharePoint and Microsoft Teams. A foundational element to this is providing users with quick and easy access to those files across devices regardless of the file type.

To support this, we’ve continued to invest in and improve our file viewing technology and currently support over 300 file types. This enables users to get high-fidelity previews and thumbnail images for Adobe formats, like Photoshop and Illustrator, 3D files or DICOM medical images without actually installing the native application.


OneDrive provides thumbnails for Files On-Demand

For customers running Files On-Demand in Windows 10, these thumbnails allow you to quickly scan through files and find what you are looking for without needing to download and open files.


OneDrive thumbnails and preview via the browser

With the OneDrive web client, if I share an Adobe Photoshop or Illustrator file with someone, all someone needs to do is open the file in any browser. That user will then get a full-screen preview of the file without requiring the actual Adobe application to be installed on that device.


Full screen video viewing in OneDrive

What’s great is we offer this experience for over 300 of the most commonly used file types. We have even added the ability to listen to audio tracks or watch videos stored in OneDrive, right from your browser or the OneDrive mobile app.
