Shredding files in windows
Probably not. Unless they added one in Windows 8
I recently purchased a new PC with Windows 7, and the manufacturer bundled a third party shredder application. I infer that either there isn't one as standard (and I've never heard of one) or (less likely?) that the manufacturer added some unnecessary bloatware without the usual sliver of justification.
It's hard to prove a negative though.
Notes:
Shred only overwrites a file, it doesn't seek out fragments and copies of the data in unallocated disk space (caused by editing, etc.).
You don't need to overwrite a file more than once. Statements to the contrary have been thoroughly debunked long ago.
It doesn't matter what you overwrite it with.
So just copying a sufficiently large but innocuous file over the top will suffice.
Update:
You could delete the file and then use cipher:
- Quit all programs.
- Click Start, click Run, type
cmd, and then press ENTER.- Type
cipher /w:driveletter:\foldername, and then press ENTER. Specify the drive and the folder that identifies the volume that contains the deleted data that you want to overwrite. Data that is not allocated to files or folders will be overwritten. This permanently removes the data. This can take a long time if you are overwriting a large space.
It's probably quicker to just copy a big file over the sensitive file, but safer to clear unallocated space.
Piriform's CCleaner offers an option to wipe out free space. File Shredder allows to wipe out a particular file "on deletion time"
**EDIT: Found something on MS' sysinternas. SDelete. Haven't tried but could give it a try.
Not Windows-native, but likely to be already installed for many people reading this question: Git for Windows comes with its own ports of many common Unix utilities, including shred. By default it's located at C:\Program Files\Git\usr\bin\shred.exe.
Usage is the same as on Unix-likes, e.g. C:\"Program Files"\Git\usr\bin\shred.exe myfile.txt
