If you came to our page looking for information on how to corrupt a file so that it won’t open on a PC or Mac, you might be under the impression that it will be a time-consuming job requiring hundreds of steps. That is clearly not the case, though. You can quickly ruin a file and save the day.
Method 1. Change File Extensions to Corrupt a File on Mac and PC
The operating system receives information about the type of files and how to operate them from file extensions.
Changing these extensions can make the operating system uncertain of the file type and prevent the file from being launched. Here’s how to corrupt a file by changing its extension:
Step 1: Click Windows and perform a folder options search.
Step 2: After entering the folder settings, select the “View” tab.
Step 3: Tick the box next to the command that says “Show file extensions” when you see it.
Step 4: Go to the file you wish to corrupt. It will have a name for its extension; for example, let’s say it’s a word document with the extension Docx.
Step 5: Rename the file with a right-click.
Step 6: Just modify the extension name and hit enter without completely renaming the file.
Now, this file cannot be run by the operating system. Moreover, this file will display an error every time someone tries to run it.
Method 2. Corrupt A File Using Notepad On Windows
With the notepad included with Windows, corrupting a word or PDF file is a piece of cake. You can corrupt the file in under a minute to avoid having your reputation damaged. Here is how to corrupt a file on Windows using Notepad:

Step 1: right-click the file you wish to corrupt and choose to open it in a notepad. Due to the file nature, Notepad could take a while to run, so be patient.
Step 2: After opening the notepad, you will find a tonne of odd commands you have never seen before; you simply need to choose 10 to 12 lines of the command from the top, middle, or bottom of the page and erase it.
Step 3: After wiping, save the document and exit the notepad application. Again, closing and keeping a notepad file may take longer than usual.
Step 4: Open the file in any file viewer to discover that it cannot be opened since it is corrupt. It will take 1-2 minutes to finish this quick process.
