Hyperspace searches for files with identical content within one or more folders.
If it finds any, it can then reclaim the disk space taken by all but one of the identical filesβwithout removing any of the files!
To do this, uses a standard feature of the macOS file system: space-saving clones. The Finder does the same thing when you duplicate a file. For more information, choose β Helpβ from the appβs βHelpβ menu, or visit#help
