Hi, I am trying to get latest data from a Folder I have always connected to. Now I get below message error.
Can anyone help?

Hi @Anonymous ,
I would suggest you checking if this folder is in use or some file inside it is using by other process.
If you can't find any other process is using this folder, I would suggest you restarting the Windows Explorer process and try again.
Best Regards,
Teige
