Hi,
To completely delete files from your computer, you need to use a tool that can overwrite the data with random patterns, making it impossible to recover. Eraser is one of such tools that can securely erase files, folders, or entire drives. To use Eraser, you need to download and install it from its official website. Then, you can either drag and drop the files you want to delete into the Eraser window, or right-click on them and select Erase from the context menu. Eraser will then ask you to confirm the deletion and show you the progress. Once the process is complete, Eraser will remove every trace of the file from your computer.
I hope this helps. If you have any further questions, please reply to this answer.
Best regards,
Megan B.
