4 Open Source Software to Delete Files Permanently

Deleting a file in Windows generally does not actually erase the content of the file, regardless of whether the file you deleted is smaller than 1KB or larger than 1GB, it will be “removed” instantly( the activity of your hard drive light exposed that ), which suggests that only the link is removed, the file itself is not affected.

To wipe your sensitive files, you will need to fill in the contents of them with zero or random bytes, you can perform it manually with a hex editor, or use one of the following programs:
