Step 2. Find a file other than a Microsoft Word file or a text document
We recommend that you use a file type that cannot be opened in Microsoft Word, such as an image file (.jpg,.gif,.png) or sound file (.wav,.mp3,.ogg). You will use this file to create a fake corrupted Microsoft Word file.
Given that the selected file will be corrupted and cannot be reopened, it is recommended that you choose a file that is not important. You can also make a copy of the file before changing its name extension if you want to keep it

Warning
- Do not use files that are important because files that have been damaged cannot be recovered easily. Therefore, it is recommended that you use unimportant files or copies of files.
- If you want to destroy the assignment file to trick the teacher or lecturer, you have to be careful. Many schools and universities already know this trick. Some teachers or professors may give you a zero if you submit a corrupted file. Read the school or university's rules and policies before you follow the steps listed in this article.
