Under Windows Photoshop is grabbing files even after they where closed in Photoshop. I get error messages from explorer that the file is open in an app when trying to delete images I previously had open in PS. When I close PS, explorer can delete the file.
Obviously PS is still somehow grabbing the file even after closing it in PS. That is not ok from a resource and usability standpoint.
The error can easily be reproduced: Open file in PS, close file in PS, delete file with explorer -> error, close PS, delete file -> success
