When you delete a file on Windows, it is done partially; that is, you lose access to that file, but the data isn't completely deleted from your hard drive (which is why there are programs capable of recovering already deleted files).
To make sure that files are completely deleted from your computer, you can turn to programs such as Secure Eraser, which takes care of providing total reliability when it comes to deleting data from your hard drive.
It has various methods of deletion, each one with a different level of security and different processing time.
In addition to file deletion, Secure Eraser also provides you with a tool for cleaning free space on the hard drive to securely delete every trace of previously deleted files, a system cleaner for freeing up space on the hard drive, and a registry cleaner.
