With NShred you can eliminate confidential information
and data from PC hard disks. Name, size, contents of
erased file or folder can never be recovered, by any
software or hardware means.

Why just deleting is not enough?

When you delete a file or a folder in WindowsTM it is
not actually erased. Simply, the hard disk descriptor
table is updated and the file entry is removed. So,
the actual bytes of the file remain on the disk. Even
when the file area is overwritten, it is still
possibile to recover data, by applying certain
laboratory procedures because it's rare that a portion
of the hard disk is rewritten more than 3/5 times. It
has been calculated that information is completely
unrecoverable only after more than 30 rewrites.

How can NShred effectively destroy any data?

NShred detects the file area on the hard disk. This
area includes metadata on file, such as name and date.
The area is then rewritten n times depending on the
procedure. For instance, with DOD algorithm, the file
area is rewritten one times with "0" bit, then
with "1" bit, then with a random byte.
After rewriting, the file area is reduced to zero, the
file renamed with random characters and finally
deleted. This procedure guarantees that not even a
single byte from the former file can ever retrieved.

Why NShred is different from other shredding tools?

While the majority of shredding tools are "brute
force" and "operating system agnostic" erasing tools,
NShred behaves accordingly to the underlying Operating
System (OS), denying the user the possibility to turn
it unstable. For instance, if the OS denies a delete
operation, NShred will NOT erase the file. The user
will be able to erase it later when it is no more
locked by the OS.
Plus, NShred is a .NET Framework smart client
application, which ensure the user with a superior
robustness and full compatibility and integration with
the latest Microsoft Operating Systems and tools.
