Finder, files, and apps
Navigate your storage and software with macOS’ convenience features
Contrary to myth, having thousands of small files all over your Mac’s startup drive won’t normally affect its performance. Nor do you need to defragment your hard disk, like in the old days — macOS takes care of that all by itself. The time to worry about space is when your drive gets within a few dozen gigabytes of full, and the place to do something about it is the Finder. We’ve also got tips and shortcuts for customizing your workspace and organizing apps, windows, files, and folders.
