I can't delete folders with long names

There seems to be a bug in CCleaner --- v5.63.7540 (64-bit) portable --- when it comes to long names. CCleaner will not delete the folder:

Bundeskanzlerin _ Aktuelles _ Rede von Bundeskanzlerin Merkel zum zehnjährigen Bestehen der Stiftung Auschwitz-Birkenau am 6. Dezember 2019 in Auschwitz_files

or any of the files within it. Presumably the folder name is too long (which Windows Delete tells me when I manually delete the folder), but long names like this unfortunately occur routinely when downloading a webpage.

* Has this issue already been addressed (I found a 2010 post along the same lines)?

* Am I missing a switch somewhere in the Configuration?

* Or am I reporting a bug?

Thanks very much for the free software, which I rely on all the time to clear cookies and old internet junk from my system.

Long filenames have always been a problem with Windows.

And as it's a Windows / OS  problem then what any software can do to help get round the problem it is limited.
