To simplify work, Box currently supports file previews and search via 1st and 3rd party applications for more than 150+ filetypes, including proprietary ones such as MS Office, Autocad, InDesign, iWork, etc.
In an effort to expand its Content Cloud, Box is adding support for 2 Docuworks filetypes (.xdw and .xbd). This will notably allow Box users to preview and search Docuworks files directly in the Box Web and Box Mobile Applications.
