How to Fix Directory with all Question Marks as Permissions
Solution 1:
This may be an issue with the mounting service (e.g. Samba). Try restarting the Samba service on the remote host:
sudo service smb restart
Solution 2:
I had this issue when running bind mounts on Docker. I restarted the Docker daemon and the file was correctly removed.
edit: I used WSL (Ubuntu 16.04) on Windows 10.
