Folder browsing

More room
for your folders.

Open a second folder when you need to copy or move files between them.

Choose one or two panes.

Use one pane for a single folder, or open a second pane alongside it. Each pane keeps its folder when you switch views.

Save your usual folders.

Save folders as favourites and open them in either pane. Click a folder in the path at the top to return to it.
