I have tried numerous ways to do this from various suggestions but they keep coming back.  I may have found a way but time will tell but it appears to be working so far.

Cut the file and paste into an external devices such as a memory card or a USB.

Remove the card or USB for a few minutes.  Then re-insert and delete the file and remove it again

So far, this seems to have worked. Have rebooted a couple of time and still no sign of the deleted and unwanted file
