Any file I uploaded to a SharePoint folder and try to preview it in the browser (either by clicking preview in browser or typing the URL directly into the browser) the browser wants to download the file instead of just displaying it. These are html files. Our Server Administrator does not know what is causing this behavior. HELP!

    Check your library settings--if the default behavior for documents in a library is to open in client rather than open in a new tab, that'll be the cause.

  1. Go to Central Administration 2013 > Application Management > Manage Web Application.
  2. Select your web application from the list and on the ribbon select General Settings.
  3. Now find Browser File Handling option in the modal pop up window and change Strict to Permissive.

Just like this

and now you should be able to view your HTML files in browser.
