How to Change File Type in Windows 10

With our increasing use of computers in our daily life, it may get necessary even for a simple user to change the file type of a file from one format to another. Each file format has their own properties. For example a ‘.txt’ file will probably get opened by the text editor while an ‘html’ file will get launched in your default browser.

Even though the contents inside the files might be the same, the file type matters a lot. The process of changing file type is quite simple and straightforward. However, there are some cases whereby changing the file type, the file becomes unusable. Hence it is recommended that you know exactly what you’re doing and also make an additional copy of the file.

Showing file extensions and changing the file format

By default, Windows doesn’t have the file format displayed alongside every file. For example, if a file is a text file, its name wouldn’t display ‘ap puals.txt’. Instead, it will only display ‘appuals’. First, we will enable the file extensions and then through basic rename, we will change the file extension. You can also choose to rename files in bulk if there are a lot of files that you need to change the type for.

  1. Press Windows + E, click View from the top-most ribbon. Now click Options and select the option Change folder and search options.

  1. Now navigate to the file for which you want to change the file format. Right-click on it and select Rename.
  2. Now change the file’s extension to the extension of the type which you want to change into. In this example, we change a ‘text’ file to a ‘python’ file. The extensions for a text file are ‘txt’ and for python ‘py’.
