Secure Delete
The Secure Delete feature is used to for deleting unwanted files or folders completely from the system. Data deleted using the
Delete function of Windows can be recovered using Recovery Softwares as the link to such data remains in the cluster of hard
drives. The Secure Delete feature of Quick Heal PCTuner deletes the file or folders directly from the hard drive making it
unrecoverable even if Recovery Softwares are used.
Deletion Methods
There are three file deletion methods available in Quick Heal PCTuner. They are:
One Pass Random – Quick
Data Destruction
One Pass Random deletion method uses random letters to overwrite
the data. This method of deletion is quick and quite secure. Data once
deleted cannot be recovered. This is the best choice for most users.
This is also the default file deletion method.
Two Pass – More Secure
Destruction
Two Pass deletion method uses twice the number of random letters to
overwrite the data. This method of deletion provides additional layer
of security. Data once deleted cannot be recovered by any recovery
software.
DoD – Standard Data
Destruction
DoD deletion uses the encryption method of using random letters to
overwrite data as per the Department of Defense Memo. Data once
deleted cannot be recovered by any recovery software.
