# Why are some identical files listed as freeing no space?

Some files look like separate copies but actually share the same storage on your disk. On Macs with the APFS file system, duplicating a file in Finder often creates a **clone** that takes no extra space until one copy is changed; **hard links** are two names for the very same file.

Removing one of those wouldn't give you any space back, so Storage Studio lists them in a separate section — *"Identical, but freeing these reclaims no space"* — and never removes them. If you try, you'll see *"These copies share storage, so removing them wouldn't free space."*

This is also why a set's "to free" figure can be smaller than the files' sizes suggest.
