Use the menu Document / Comparison/Merge/Open again... (to replace current view) or the
Document / Comparison/Merge / Open
similar...(to open an additional view)
When you use these options the Open box is automatically
filled with the current paths. You can modify slightly the
paths or let them as is.
The comparison settings will be reset to application
defaults.
You can also select another path in the source combo (or
modify it directly in the text field), or use the Browse command
to select anoth path (file or folder).
In addition, the macro button 'Go up in hierarchy' of the
Folders toolbar can be used to make all the sources use their
parent folder (when used on a non-folder document, a new window
is opened with the container folder browser or comparison).
In a
Folder Comparison, if you wish to move the base folder in one
of the source toward a displayed folder in the tree view, drag
and drop it with the mouse on the combo.
