Set or Change File Associations & Extensions in Windows 10 / 8 / 7

Each file in your Windows operating system has an extension in its filename eg. .txt, .doc, etc. These extensions are used to identify the program, with which, windows can open this file. You can set or change these file associations in your Windows. In Windows XP you had this setting to change file type associations in Folder Options. In Windows 10, Windows 8, Windows 7 and Windows Vista you don’t see it there, though.

Change file associations

To set File Associations in Windows 8 / 7, Open Control Panel > Control Panel Home > Default Programs > Set Associations. Select a file type in the list and click Change Program.

You will be displayed a list of Programs along with a Description and the Current Default. You can click on the Change program to set or change the current defaults.

Alternatively, you can also right-click the file whose association you want to change > Properties > General tab > Type Of File > Change > Choose a program from the list or recommended or other programs or else click Browse to select one.

If you wish, you can also set, reset, change File Associations & extensions easily with this freeware.

Types is a free and lightweight configuration utility for Windows that allows you to edit program associations, icons, context menus and other properties of various file types displayed in Windows Explorer.

It is a worthwhile replacement to the inbuilt Windows file type utility.

    What ever happened to the file association option that could be used when editing a file? You were able to use a different program to open as opposed to edit a file.

    Thank you soooo much you saved me from a reformat. I was getting this weird .cpl file association error (blocking me from loading windows control panel and also blocked me from associating files in the start menu). For some reason your tool just clicked and saved my associations and I was able to repair my computer. (I think it was malware from Wise365) any rate thank you so much! I’m glad you guys are still around!

    why are new .java files created as text .txt files when done in notepad by default how to overcome it

    Right click on the file name and choose, “Open with.” Go down to “Set Default Program.” Choose the program that you want to use from the available options, or select “Search” to look for a different program.

    I clicked to open a photo today, and my Window photo gallery program is gone? Just missing completely. I went to Microsoft to attempt to download it again and it read that I already had it installed. Can anyone help me with how or why this could happen? I have a external hard drive and an image restore and blah blah which nothing opens from it, that is why I came here to read about the file extensions but thought I would ask everyone about my problem.

  • Holger

    This not an answer to the question. The question is how to set the ‘edit’ program, not the ‘open’ program. Does anyone know where to set that?
