A file shredder is a software tool designed to permanently delete files from your computer. Unlike the regular delete function, which only moves files to the recycle bin, a file shredder overwrites the data multiple times, making it nearly impossible to recover. This is especially important for sensitive information, such as personal documents or financial records. Using a file shredder helps protect your privacy and ensures that confidential data is not accessible to others. Whether you're selling your computer or just cleaning up, a file shredder provides peace of mind by securely erasing files that you no longer need.
