Audio and Video

Support for video preview is dependent on the capabilities of the browser, with a fallback to Flash for supported formats.

For the best video compatibility, we recommend mp4 files with h.264 encoded video and AAC encoded audio.

Audio and video files are not supported for File Links with the "Download" option set to "No". For more information, please, refer to the article about preview-only links

gdoc, gsheet, gslides, gdraw

You must be using our Google Drive or G Suite integration to preview Google file types. File links for Google documents (gslides, gdoc, etc) are opened in a PDF previewer. This is by design.

Preview with Integrations

Certain third party applications (for example Microsoft Office Online) are able to generate file previews for their native file types in the Egnyte Web UI. Because such applications are designed specifically for their file types, they may offer a better user experience for previewing these file. To generate a preview, Egnyte must pass a copy of the relevant file to the third party application developer.  The preview capability is turned on by default once you enable an application that supports the preview capability.

If you prefer to use Egnyte's own preview capability or to avoid passing files to the relevant application providers, domain administrators can turn off the third party preview capability from the Egnyte Settings page. To do so open the Settings page, select the General tab, find the Previewing Files option and select it to disable.
