How To Configure Unknown File Types For Download In IIS (ex. ".dmg" files)



TODO:

Have you ever tried to allow uses to download a file, for instance a .dmg file, but your users could not do so?  This happens because the .dmg file type is not defined in the MIME Type Settings in IIS.

 

SOLUTION:

  1. Open IIS
  2. Click on the site affected.
  3. Click "Mime Types"
  4. Click "Add"
  5. Enter ".dmg" in the file extension text box (no quotes)
  6. Enter "file/download" in the MIME type text box (no quotes)
  7. Click "OK" and you are done.  Your users will now be ble to download .dmg files from your web server.

These instructions are for IIS version 7
