Secure Delete Files

In spite of the fact that you remove it and can no longer access it, when you delete a file in Windows you are only removing its reference from the file system. Since the data is still on the hard disk until other data overwrites it, it means that it can be recovered.
Secure Delete Files is a lightweight application that enables you to permanently erase the data from the file system table and hence, eliminate the risk associated with the file being restored and the data made accessible again.

Straightforward functionality, yet does not include a UI

You should know that the program does not include an interface, but it integrates into the context menu of Windows Explorer. Even though it relies on one of the most reliable deletion algorithms, the lack of a UI could make some users reluctant regarding the overall efficiency of the app.
While the idea here is to make wiping data as simple as possible, it would have been nice if the app included an interface where you can process multiple files at the same time. Then again, the simple fact that you can access it from the context menu any time makes things more convenient and faster.

It relies on the Bruce Schneier algorithm for deletion

It is necessary to mention the program uses the Bruce Schneier algorithm to erase the files. In case you did not know, the algorithm entails that the data is deleted 26 times and then random data is overwritten on it 5 times.
Therefore, you can be sure that the data deleted cannot be recovered with other third-party software solutions. Although not as efficient as a deep hard disk formatting, it is an option worth considering.

A simple utility for wiping files and keeping your privacy

In the eventuality that you are commonly working with files that contain sensitive data on your personal computer and want to make sure they are unrecoverable after you erase them from your computer, then perhaps you should consider trying out Secure Delete Files.
