OS: Windows 7 - 64bit
When dragging and dropping an image file in the file list the file is copied even though the drag&drop is on the same disk/drive.
Effect: Unexpected behaviour
To reproduce:
1. Open XnView browser and navigate to a folder which contains an image file and a sub folder.
2. In the file list (on the right) drag the image file to the sub folder in the file list and drop it.
Actual behaviour (bug): Image file will be copied to the sub folder.

Expected behaviour: Drag & Drop one the same drive must move the file / folder.
