Step 1: Double-click the file.

Locate the MDF file icon and double-click it. If you have the right program installed, it should open the file automatically. If it doesn’t, move on to Step 2.

Step 2: Look for another program.

If the MDF file doesn’t open when you double-click it, you probably don’t have the right program on your computer. There are several popular programs that can be used to open a MDF file. Try one of the three most common programs: ProWORX Nxt Memory Data, Star Trek Armada Map File Title & Image Information, or I-deas Master Drafting Machine Data File.

Step 3: Check the file type.

If none of the above programs will open your MDF file, check the file type to make sure you have a program that can open that type of file. Most MDF files are Misc Files, but there’s a chance it might be another type.

You can find this information in the file’s properties. On a Windows computer, just right-click the file and click properties, and look for the file type under “Type of File.” On a Mac computer, right-click the file and click “More info,” and look for the file type under “Kind.”

Step 4: Get help from a developer.

If you can’t figure out how to open a MDF file, a developer can probably tell you how. Find the program you have in the table below and contact the developer of that program.

Program Name Developer Name
ProWORX Nxt Memory Data Schneider Electric
Star Trek Armada Map File Title & Image Information Unknown

Alcohol 120% CD Image File Alcohol Software
Vector CANape / CANgraph / CANdito Measurement Data Vector Informatik GmbH
Capture Classic Filler Accelio
Insight II Molecular Data File Accelrys Software Inc.

Step 5: Find a universal file viewer.

The easiest way to open a MDF file, or any kind of file, is to use a universal file viewer like File Magic (Download). You can use it to open many different file formats. If it’s not compatible, the file will just open in binary.
