File type not being recognized


  • When I try to download a file, it appears that Internet Explorer 9 doesn't recognize the file type. I get the option to open or save as when I try to download the file. If I choose to open it, the file opens in another Internet explorer window. If we try to Save As, the download doesn't complete. It appears that IE is renaming the document, so if the file name was document.csv, it appears that IE is changing that to document_csv.
    We are running this on Server 2008.

  • Hi,

    1. Ensure you are using the default security settings in IE.. Internet Options>Security tab, click "Reset all zones to default".... there are settings for mime-sniffing.

    contact the website that hosts the download.... they have incorrect content-length headers. (f12>Networking tab, click "Start Capturing" (IE9))

    for questions about html, css and scripting for web site developers post to the IE Web Development forum with a link to your website or a mashup that shows the issue.
