RightDelete

RightDelete is a tiny software application that can permanently delete files and folders from your computer. This way, they cannot be recovered though special programs.
This is a portable tool, so installing RightDelete is not necessary. It means that you can store it on a USB flash drive or any other removable device, save it to any computer and directly run its executable file.
Therefore, you can always carry RightDelete with you when you're on the move. What's more important is the fact that the Windows Registry does not receive new updates and no leftover files can be found on the hard drive after program removal.
The interface of the configuration window is user-friendly. There are no other features to be found except for the ones available through the main application window.
So, you can integrate RightDelete into the Explorer context menu, as a file/folder link or 'Send To' link. Additionally, you can allow the tool to create a desktop shortcut. If you have not disabled the options in the configuration area, and removed the app from the computer, you will still be able to securely delete files and folders.
The software app uses a barely noticeable amount of CPU and system memory. It deletes file through the seven-pass method. We have not come across any errors during our testing; RightDelete did not freeze, crash or pop up error dialogs. Thanks to its intuitive layout and overall simplicity, first-time users may seamlessly get accustomed to the tool's features.
