While the default file associations work pretty well, there are times when you might want to replace them with third-party programs. In this guide, we’ll take a closer look at Windows files associations and share the different methods you can use to change files associations in Windows 10.
What is Windows File Association?
File association is an essential component of an operating system that associates different kinds of files supported on your system with compatible applications, so you don’t have to manually select the right program for a file every time you want to open it. All major operating systems—Linux, macOS, and Windows—have their way of implementing file type associations. Talking about Windows, in particular, the operating system uses the “open” verb to invoke the associated program for a file type and present it to the user to perform an edit or some other action. All file associations on Windows 10 are stored as sets of verbs in the Windows Registry, and you can change these associations based on your preferences.
Determining File Associations of a File Type
Before you jump in and start changing the default program on your system, you first need to determine the current association for the file type whose default application you want to change. To determine file associations of a file type, open File Explorer and navigate to the folder that contains files of the file type you want to modify. For example, if you want to find out the default file association for the .txt file type, go to a folder that contains text (.txt) files. Next, right-click on a file and select Properties from the menu. In the Properties window, check the values against the Type of file and Opens with fields. Type of file, as its name suggests, tells you the file type and its extension. In our example, it’s Text Document.
On the other hand, Opens with identifies the current program or application assigned to open the selected file. In our case, this is Notepad.
How to Change File Associations in Windows 10
Microsoft offers three ways to change file type associations in Windows 10, each with its own advantages and scope of use.
1. Changing File Associations Using Open With
If you’ve been a Windows user for some time, you’re probably already aware of the Open With method: it’s the easiest way to change file associations on Windows. Follow the steps below to change the default file association using Open With: If, for some reason, you don’t see your desired program on the list, scroll down and select Look for another app on this PC. Then, use File Explorer to navigate to the installation path of the program you want to use, select it, and hit OK.
2. Changing File Associations Using Settings
Windows 10 Settings offers a more granular way of managing file associations on your PC. It presents you with all the different file types in use so you can change their default programs with ease. Moreover, you also get the ability to change the default apps for email, music, maps, and web browsing, among others. For changing file associations from Settings, use the following steps: With this method, you can also choose the Choose default apps by protocol and Set defaults by app options in step 2. While the former allows you to choose the default program for actions or links, the latter lets you manage an entire program (associated file types and protocols).
3. Changing File Associations Using Command Prompt
Even though both the methods we’ve listed so far do the job, if you want a quick and efficient way of changing file associations on your computer, you should consider using the Command Prompt. To use Command Prompt for changing file associations, follow these steps: If the output returns Notepad or the application name you set for that file type, you’ve successfully changed its file association. In case it doesn’t, perform the steps again.
Resetting File Associations in Windows 10
If you’ve misconfigured file associations, you can reset them to change their file associations back to the default apps. Follow the steps below to reset app defaults in Windows 10.

Additionally, since it presents you the entire list of different file types and their associated default applications, you get to manage pretty much all file extensions with ease in one place.
