SDelete GUI is an Open Source app that provides an alternative option to the command-line only SDelete from Sysinternals.
But to be clear, SDelete GUI uses Microsoft Sysinternals SDelete to perform file and folder deletions via the DOD 5220.22-M algorithm. But for those that are not comfortable performing the deletion process via the command-line, this will be perfect.
SDelete GUI allows you to add a "Secure Delete" option in the Windows right-click context menu. The Secure Delete addition will securely and permanently delete all selected files and folders.
SDelete GUI will download SDelete from Microsoft (or get SDelete from MajorGeeks in advance) to work properly. If the download fails, it will check if you already have SDelete in your System32 or SysWow64 folder. If either downloading or searching for it do not work, SDelete GUI will not work properly.
SDelete GUI is a simple way to gain the functionality of a tested and trusted program such as SDelete but with the added benefit of a UI and context menu integration.
Please note, there is NO confirmation dialog before performing a deletion. Once you click on it, all the selected files and folders will be deleted.
