By default, the Viewer sends Open Document requests with the generic mime type “application/octet-stream.” Microsoft Internet Explorer then opens the requested document with the supplied file extension. You can map additional mime types or turn off mime type mappings by modifying the Mime Types registry sub-key in Windows Registry.

• To map additional mime types, create additional string values under this registry sub-key:

  HKEY_LOCAL_MACHINESOFTWARESolidWorksSolidWorks 2009PDMWorks WorkgroupWebPortalMime Types

  in the form:

  “ext” = “mime type”

  For example:

  "dxf" = "image/vnd.dxf"

  You must manually create this registry sub-key before you add the values.

  To turn off mime type mappings, change the Use Custom MIME Types registry value to 0 (zero).

  HKEY_LOCAL_MACHINESOFTWARESolidWorksSolidWorks 2009PDMWorks WorkgroupWebPortalUse Custom MIME Types

  Restarting the web server is not required to activate this setting.
