Need to use third-party programs to open files on your PC? Here's how to change file associations in Windows 10 and choose which apps open which file types.

The Windows 10 File Explorer offers a handy tool called Preview Pane. Though this feature, you can preview many different types of files without having to open them in their associated applications.

Windows makes it easy for you to open up these files by setting up default programs for each file type -- images files, for example, will open by default in the Windows 10 Photos app.
