Only after many searches I stumbled over this thread.
There are many file shredders around.
However, 'taking care' of MFT records (erasing, wiping, or whatever) when doing a secure delete of files or folders is hardly being mentioned.
Yes, one can wipe the free space of an entire HDD, which takes a lllong time, whereas in fact users may wish to secure delete just some files or folders only and have the MFT records also wiped/erased.
Specifically this matter is not listed in the feature list of the products.
It may be useful to add this to the feature list.
Just a tip only.
