I copied a plain-text file (extension .txt) and pasted it on my Windows desktop as erase-test.txt. Using Notepad, I added several lines of random text. Then I waited several minutes.
I selected the file erase-test.txt, right-clicked, and selected [Eraser > Erase] from the pull-down context menu. On the Erase Items popup dialogue, I selected the Yes button. The file erase-text.txt disappeared almost immediately from my desktop. Afterwards , the Eraser window contained test-erase.txt with its complete path under Task Name along with "Queued for execution" as the Next Run. Terminating Eraser (confirmed with Task Manager) and then launching it again did not remove that task.
Selecting that unwanted task, right-clicking, and selecting Run Now from the pull-down context menu caused the task to disappear. There was no error indicated.
After all that, I repeated this test. This time, I used Task Manager to verify that Notepad was not running and that Windows Explorer was quiescent. That was to determine that the erase-test.txt file was not in use. The results were the same as above.
NOTE WELL: I was a software test engineer for 30+ years before I retired. I tested very complex software systems used by the U.S. military to fly its space satellites. During that time, no satellite failed from a software problem if the organization in which I worked had tested that software.
