Vainly tried to find a solution on Internet.
The below may be a very long shot and not possible at all...
It is a regular occurrance that I control-left-mouse-click select files.
Guess that I am clicking slightly too fast, so often I accidentally COPY all the files.
Have to pay attention to it that it won't happen.
They should be deleted afterward (details mode, sort on filenames, delete, or maybe ctrl-z)
I use ctrl-c/v to copy.
Is there any setting that prevents this ctrl-left mouseclick copy action from happening?
