This is a really common issue with windows. You can try turning off backups/virus scanning of that folder and sometimes this relieves the issue. (I assume there is a file attribute you can alter.) It's probably the case that Kafka itself has the file open, as linux does not have issues if you move a file while it's being written to or open.
If you are interested in the locking process (and tools that help you delete or 'unlock the file' on windows see this post <https://superuser.com/questions/117902/find-out-which-process-is-locking-a-file-or-folder-in-windows>.) Might also help provide enough information for you to file a bug in jira against the issue. Hope this helps. On Mon, 17 Jul 2017 at 04:45 M.
