Unless you know the exact path to the Word back-up files - and create a special task for erasing it, anEraser free-space wipe's not going to touch it - because you're right, it's not
un-used disk space. The same goes for some
of the other files you mentioned.
In the case of the Word back-up files, CleanCache offers to securely over-write the MRU's involved (I have no idea whether or not that actually erases the backed-up file itself or what, I've never checked it since Word docs on here aren't a concern).
Both Eraser and CleanCache will
(if correctly set) erase the swap file or pagefile.
Clean Cache - http://www.buttuglysoftware.com/CleanCache3.html
- in addition will clean UserAssist registry entries
CCleaner - http://www.ccleaner.com/
- (if so set) will erase - among other things - Memory dumps, ChkDisk File Fragments, Windows Log Files, Old pre-fetch data and User Assist History, as well.
Index.dat Suite - http://support.it-mate.co.uk/?mode=Prod ... x.datsuite
- will flush your DNS cache - among other things - if so set.
IOW, an Eraser free-space wipe's not going to touch anything
that either hasn't been already normally manually deleted or securely over-written first
(before a free-space wipe with Eraser) unless, of course, you've created
- with correct paths - a task within Eraser itself to do
I use all three above-mentioned programs (along with another thing or three) prior
to any Eraser runs.
So why use Eraser at all, you say? Because of all the programs I just mentioned only Eraser will securely erase the file names and sizes and types
that were deleted "securely erased" by the other programs so that that
information can't be recovered by forensic recovery programs. HTH Pete
