Permadelete is a new open source program for Microsoft Windows devices that you may use to remove files securely from the PC.
The delete operation on Windows does not really do what the majority of users expects it to do. Instead of removing the contents of a file and its reference from the system, delete simply removes the reference but leaves the contents on the disk.
The parts of the disk are set to write again, so that data may overwrite the deleted file eventually. Until that is the case though, file recovery tools may recover the deleted files completely or partially.
