Viewer-supported file types

Relativity uses the Viewer to display rendered versions of native files. Reviewers can see how the file looked in its native application without opening the file in that native application.

When converting email file types such as EML, the Viewer will not download images from the internet. Any linked images will display as a gray box in the Viewer.

This page provides a comprehensive list of files types supported by the Viewer. Find out which Viewer version you have, by navigating to your Viewer and clicking . For more information, see Viewer.

Note: Relativity does not support any third-party applications after the user downloads a file. This includes specific browser and media-player combinations, such as Internet Explorer and Windows Media Player.

This page contains the following:

Text only designation

Some file types have a "text only" designation. When viewing these files in the Native Viewer, the document's text is the only data that renders. For Microsoft Project files and XML files, the view doesn't display items such as Gantt charts, icons, or other graphics. There is typically no formatting (bold, italics, fonts, etc.) of the text.

File ID only designation

Some file types have a "file ID only" designation. The Viewer is able to identify the file ID correctly, but it returns an error message indicating that the file format is not supported. Despite returning an error message, the Viewer identifies the file so that you can easily locate it and open it in an alternate application.

MBOX Mailbox

Note: Any MBOX file that is ingested into Relativity using the Relativity Desktop Client will display as an archive, regardless of how many messages it may have or what extension it might have. An MBOX file is characterized as a text file with the string "From<space>email address<space>date string". When a file of this nature is viewed in Relativity, it may appear to only show summaries of messages. Essentially, if that "from" line is at the top of the document, Relativity treats it as MBOX and displays it as an archive.
