Summary: By default Directory Opus emulates standard Windows behaviour so that a drag & drop between directories on the same drive results in a move while a drag & drop between different drives results in a copy. If desired, this behaviour can be changed.
If you use drag & drop Directory Opus will mimic the normal Windows Explorer behaviour of moving files when on the same drive. Unlike Windows Explorer, in Opus this and other actions are easily changed. The action is fully configurable and controlled by the drop action of the All Files and Folders File Type.
Before you start changing File Types remember that drag & drop is only one of the ways that you can copy or move files within Directory Opus. Opus has the concept of source and destination windows (or sides of a dual-file-display window) which allows you to select files in one window and then click the Copy or Move button on your toolbar to perform the appropriate action.
Note: Drag & Drop is handled by the window that you drop on to. If you drag from Opus to an Explorer window – including an Explorer window that is inside Opus, such as the virtual Desktop folder – then Explorer’s rules will be applied. (In the Desktop case, if you navigate to /desktopdir instead of Desktop then you don’t have to worry about this.)
With that said, here’s what to do if you want to change Opus so that drag & drop always results in the same action regardless of which drives are involved:[ol][li] Open the Opus File Types dialog (Settings, File Types… in the default menus).
[li] Double-click the All files and folders type near the top to open the file type editor.
[li] On the Events tab, double-click the event you want to edit. In Opus 9 it is called Drag-and-Drop and in Opus 8 it is called drop.
[li] By default the event will run the command Copy MOVEWHENSAME and you should change it either to Copy on its own or to Copy MOVE depend on whether you want to always Copy or Move on a drag & drop.
[li] Click OK in both dialogs and then close the File Types dialog.
[/li][/ol]Note that there are also actions defined for Shift Drop, Ctrl Drop, etc. as well. Check out what these do as well as the Drop Menu
tab which allows you to edit the menu shown when you drag & drop using the right mouse button.
