Recently I tried to delete a stuck file in Explorer which produced the error 

Could not find this item , This item is no longer located in xxxxxx

I tried to user Command prompt, file unlocked and reboot the server to see if System had locked the file all unsucessfully.

In the end I have to use command prompt to rename the Parent Folder of the file

ren “Parent Folder Name” “Test”

This cleared and removed the file if not you should be able to delete this in Comand prompt and explorer , I was then able to rename this folder back or delete the folder if needed.
