# Should I remove duplicates or move files to an external drive to free space?

Often both, because they solve different problems. Removing duplicates frees space you were wasting on identical copies — nothing you need goes away. Moving folders to an external drive frees space taken by files you *do* want but don't need on your Mac every day.

How much duplicates free depends entirely on your files; the Duplicates window shows the exact figure for your Mac before you remove anything. A good order is to clear duplicates first (so you don't move copies you'd later delete), then move what's left that's big and rarely used.
