Step 2. Once you are in the folder options, click on the tab named 'View".
Step 3. Now, you will see a box in front of a command saying Show file extensions; tick this box.
Step 4. Now go to the file you want to corrupt, and it will have an extension name at the end; suppose it is a word file with the extension name Docx.
Step 5. Right-click on the file and rename it.
Step 6. Don't rename it fully; just change its extension name and press enter.
Now, the operating system won't be able to run this file. Moreover, whenever anybody tries to run this file, it will show an error.
