I had Microsoft SQL Server Express 2012 installed already. I just installed the Microsoft SQL Server Management Studio Express and tried to open my mdf file. I get an error message that says:

There is no editor available for 'C:\Inetpub\wwwroot\intranet\app_data\intranet.mdf).

Make sure the application for the file type (.mdf) is installed.

Did I do something wrong? I just clicked through the defaults in the Management Studio Express install.

How can I get this to work?

An MDF file is a disc image saved by a disc authoring program such as Alcohol 120%.

It stores the actual CD or DVD disc data, while the header and track information is stored in a corresponding .MDS file. MDF files are similar to .ISO files, but are saved in a different format.

If You know, that you have installed application which can open that file, may be that this file extension is not enabled or registered. You must enable it manually.

Well...that file extension may be several different things.  I recall such as MS Access files.  More info at https://fileinfo.com/extension/mdf .

 

See https://stackoverflow.com/questions/1175882/what-is-an-mdf-file.

Microsoft access can open MDF files.
