Ever been annoyed when a certain file type, say a PDF, always opens with a program you barely use, even when you have a perfectly good one you prefer? It’s like having a fancy wrench in your toolbox but always reaching for a rusty old screwdriver for every bolt. Well, Windows 10 lets you take control, deciding which program handles which file. You can usually change a file association by right-clicking the file, selecting “Open with,” and then choosing your preferred program. For a more permanent change, head into the Windows Settings, navigate to “Apps,” and then “Default apps.” From there, you can pick which programs open specific file types, giving you full command over your digital experience.
Tutorial – How to Change File Associations in Windows 10
Changing file associations in Windows 10 means telling your computer which program you want to use for certain types of files, like images, videos, or documents. This tutorial will walk you through the most effective way to set your preferred default applications, making your computer work exactly how you want it to for different file formats.
Step 1: Open the Settings App
Start by opening the Windows Settings app on your computer.
You can do this easily by clicking on the Start button, which looks like the Windows logo, typically found in the bottom-left corner of your screen. From the Start menu, look for the gear icon labeled “Settings” and click it. Alternatively, you can press the Windows key and the ‘I’ key on your keyboard at the same time for a quicker shortcut to the Settings menu.
Step 2: Navigate to the Default Apps Section
Once Settings is open, click on “Apps.”
After you’ve clicked on “Apps,” you’ll see a menu on the left side of the window. You need to select “Default apps” from that list. This section is your command center for telling Windows which programs should handle your emails, music, photos, and web browsing, among other things.
Step 3: Choose How You Want to Set Your Defaults
In the “Default apps” section, scroll down to find different options for setting defaults.
You’ll see a few ways to tackle this. For example, you can “Choose default apps by file type,” which is usually the most useful option for our goal of changing specific file associations. There’s also “Choose default apps by protocol” and “Set defaults by app,” but for changing how a .jpg or .pdf opens, “Choose default apps by file type” is your best bet.
Step 4: Select the File Type and New Default App
Click on “Choose default apps by file type” and scroll to find the file extension you want to change.
Once you click this, a long list will appear showing every file extension Windows knows about, like .doc, .mp3, or .png. Next to each one, you’ll see the current program that opens it. Find the file type you want to change, for example, .pdf. Click on the current program listed next to it.
Step 5: Pick Your Preferred Application
A small pop-up menu will appear, listing all the compatible apps installed on your computer.
From this list, click the program you’d prefer to use as the default for that file type. If the app you want isn’t listed, you might need to click “Look for an app in the Microsoft Store” or “More apps” to browse your computer for other programs. After you select your new app, the change is instant, and Windows will remember your choice.
After you complete these steps, any time you double-click a file of that specific type, it will now automatically open with the program you just selected. No more frustration with the wrong app launching, your computer will now listen to your preferences!
Tips for Changing File Associations in Windows 10
- Always have multiple compatible apps installed: Having a few choices for opening common file types, like different photo viewers or text editors, gives you flexibility and a backup if one program acts up.
- Use “Open with” for one-time changes: If you just want to open a file with a different program this one time without changing the permanent default, right-click the file, select “Open with,” and choose your desired app. You can also check the box that says “Always use this app to open .[file extension] files” to make it the new default on the fly.
- Understand file extensions: Knowing what a file extension means (like
.exefor an executable program,.jpgfor an image, or.txtfor a plain text document) helps you understand what kind of program should open it. - Beware of unknown file types: If you encounter a file type you don’t recognize, be cautious about associating it with an unknown program, as this could potentially lead to security risks or system instability. Stick to trusted programs for common file types.
- Reset to Microsoft recommended defaults: If you’ve made a mess of your file associations or just want a fresh start, you can scroll to the top of the “Default apps” section in Settings and click “Reset all default apps to the Microsoft recommended defaults.” This can be a quick fix for many issues.
Frequently Asked Questions About Changing File Associations
Why won’t my preferred app show up in the list when I try to change the default?
Sometimes, an app you’ve installed might not automatically appear in the list of choices for a particular file type. This often happens if the app wasn’t properly registered with Windows during installation or if it’s a very new or niche program. You might need to browse for the app manually by clicking “More apps” at the bottom of the list and then “Look for another app on this PC” to navigate to its installation folder.
Can I set a different default app for the same file type, but for specific files?
No, generally, file associations are set for the file type (the extension, like .jpg or .docx), not for individual files. Once you set a default for .jpg files, all .jpg files will open with that program. If you need to open a specific file with a different app just once, use the “Open with” option by right-clicking the file.
What if I accidentally set the wrong default app?
Don’t worry, it’s easy to fix! Just go back to the “Default apps” section in Settings, navigate to “Choose default apps by file type,” find the file extension you messed up, and select the correct program again. It’s a quick reversal, so there’s no harm done.
Is it possible to completely remove a default app association?
You can’t really “remove” an association without setting another one, as Windows always needs a program to open a file type. However, if you want to undo a custom association and go back to what Windows originally suggested, you can often pick a built-in Windows app like “Photos” or “Paint” for images, or you can reset all defaults as mentioned in the tips section.
Does changing file associations affect all user accounts on the computer?
No, file associations are generally set on a per-user basis. If you change a file association on your user account, it will only affect how files open when you are logged in. Other users on the same computer will have their own default app settings, so they can customize their experience without affecting yours.
Summary of Changing File Associations
- Open the Settings app.
- Navigate to “Apps” then “Default apps.”
- Click “Choose default apps by file type.”
- Find the desired file type and click its current app.
- Select your new preferred application.
