Moving folders · Data Parking (the two-pane mover)
What happens to folders inside a folder I relocate?
Short answer: They stay where they are. Relocate keeps the whole folder tree on your Mac and replaces only the files inside with links, so the layout is unchanged. Empty folders are simply left as they were.
They stay exactly where they are. Relocate keeps the whole folder tree on your Mac — every folder and subfolder — and replaces only the files inside with links. That's why tools that walk through folders still see the same layout.
A folder that had no files in it simply stays as it was; Storage Studio reports "There were no files inside it to link". Folders themselves take almost no space, so keeping them costs nothing.
