Right-Click drag/drop for file copy does not work as expected

[Tim G]

Open FileZilla to an existing site. Local site is on left as a folder in Windows C: drive file system. Remote site is on right.
From a Windows Explorer window, attempt to copy a file from an arbitrary folder on the local drive to the Local Site folder by drag and dropping into the file list in FileZilla on the Local Site side. The Windows default is to Move, not Copy, for drag/drop on the same drive.
The common technique for achieving the non-default operation (in this case copy), is to drag with a right mouse click. This works between Explorer windows and folders, but does not work with FileZilla.
Right-click-dragging a file into the Local Site folder on the same drive results in the "Move file" dialog (incorrect), not the "Copy File" dialog (expected).

Workaround is to open an additional Windows Explorer window to the same folder as the Local Site in FileZilla. Then right-click-drag-drop of the file to the local site results in a context menu offering the choice of Move here, Copy here, or Create Shortcut here.
