DeletionTool

In some cases, files and folders cannot be deleted using the usual means, whether because of naming issues or due to the fact that they are currently in use. Fortunately, there are applications out there that can help you remove them.
DeletionTool is a very lightweight piece of software designed to help you remove items that can’t be deleted for whatever reason. It does not need to be installed and can remove either files or folders very quickly.

Delete any file or folder that you are having trouble removing

Very little documentation is provided, so it isn’t terribly clear how the application works. However, we know that it is capable of removing items that are currently in use or have names that end in special characters.
Of course, you should be very careful not to delete files that are still necessary, as the program removes them without sending them to the Recycle Bin.

Relies on simple drag and drop actions

The user interface features a simplistic visual design, and you can delete anything by simply dropping them inside the main window, checking the Delete box and clicking OK. The process is pretty much instant, and a confirmation message is displayed when the job is completed.
Alternatively, you can create a shortcut to the program on your desktop and use it to drop any file or folder you wish to delete. The GUI will not be brought up, but no confirmation is required either, so you need to be very careful not to delete something by accident.

Small, open-source program that can help you delete troublesome items

On the whole, DeletionTool is a very helpful tool that doesn’t require too much effort to use. It enables you to remove items that cannot be deleted through normal means, and it is not at all difficult to use, but it lacks documentation.
