Way 2. How to Corrupt A Word File by Changing Extension

File extensions indicate the type of file format or the data contained within. They usually follow a period (.) and consist of three or four characters. When you want to corrupt a file, you can rename the extension.

While simply renaming a file's extension doesn't corrupt the file itself, some apps might refuse to open a file with a mismatched extension. Moreover, if you force the opening or saving of the file in a different format without properly converting it, you might end up corrupting the file or losing data.

Check to learn how to corrupt a Word file by changing the extension.

1. Go to the folder where the Word file is located > Click the View tab > Check the box next to File name extensions. In this way, you will see the file extension after the file.
