Deleting files is easy! But so is restoring them. Today, we're looking at tools to help securely and safely delete and restore files.
Welcome to HakTip -- the show where we breakdown concepts, tools and techniques for hackers, gurus and IT ninjas. I'm your host shannon morse and today I'm looking at how to safely and securely delete and restore your files.
To restore files previously deleted from your recycle bin, you can use Restoration or Recuva.
Run Restoration as an administrator to search deleted files or even old files on a newly formatted card or drive. This tool is great in the fact that it's so simple and there isn't an install, so you can use it on a flashdrive. It's cons are it won't find everything and doesn't have a vast interface for really extensive searches.
Recuva also works for restoration. Recuva can do a simple scan or a complex one, depending on if your file hasn't been found by previous scans. Although this tool does require a download, it's more advanced technical GUI can make searches much easier to dwindle down to a few results.
Hitting delete just removes the references to that file from the file list. The file is still there until some data gets written over it. and even then it's still not deleted completely. So you need a tool to finish those files off for GOOD. First off is Eraser. Eraser works with any drive on your machine, it's customizable, and you can schedule erases. I like that you can choose the erasur method and you can replace files with new files to allow 'plausible deniability'. Heh, cute.
Last is SDelete. This command line tool uses the Dept. of Defense standards for securely deleting files. Being a simple command line tool, SDelete doesn't take up any space and runs without issue on any windows box. It doesn't have the smooth interface of Eraser, but it is streamlined and simple to use.
