How to Open a File With the EX File Extension

If you're looking to find out how to open the EX file extension, you've come to the right place. In most cases, Windows will open a file in the associated program, but some files fall outside of those parameters. Keep reading to find out how you can open your EX file on both Windows and Mac.

Problem: You Can't Open EX Files

You might've double-clicked on the file, to be greeted with the "Choose a program to open the file" message. In some cases, you might be able to open the file, but the contents may seem garbled and that's because it was written to be opened in a specific program. Of course, you can't open a EX file with just any software. Not to worry - we have you covered!

Step 1: Find Out Which Software Uses EX Files

Computer Files

Opening your EX file starts with understanding which software uses a EX extension. In many cases, different types of software may use the same file extensions, also known as file associations.

Unknown Apple II File, Symantec Ghost Template File, and EPM Macro File are the most popular software packages that use EX files. Therefore, your best bet would be to download one of these software packages and use one of them to open your file.


Zipped files tend to require special handling and may require password access. Contact the file owner or the person who gave you the file for the password and unzip the file before attempting to open the contents.

Step 2: Learning More About EX "File Type"

If you can't download Unknown Apple II File, Symantec Ghost Template File, or EPM Macro File software, or if they don't work to open your EX file, you may be able to use the file type as a clue to finding out how you can open it. Using a Windows PC, you can right-click and navigate to "Properties" and then to "Type of file". On a Mac, select "More info" and "Kind".

Most likely, you will find that EX files are considered Developer Files. Because many programs packages utilize Developer Files, you might be able to find a program on your computer that handles those types of files.

If that still does not work, you may have to contact the associated software developer to find out how to open it. Unless you know the specific developer, you could contact one of these developers for assistance.
