File shredding is a process used to permanently delete files from a computer or storage device. Unlike simply deleting a file, which can often be recovered using special software, file shredding overwrites the data multiple times. This makes it nearly impossible for anyone to retrieve the original information, ensuring that sensitive data remains secure. Many people use file shredding when disposing of old computers or when they want to protect their privacy. Tools for file shredding, often called file shredders, are available as software applications that can be easily installed. By using these tools, individuals can confidently erase their personal information and confidential documents.
