With daily use Mac hard drives fill up with many more files than you specifically save and create.
Every time you browse the internet, install and use apps, upload music and edit videos many more “helper” files are generated and stored on your hard drive than you realize. Every image, media file and document you “just view” online or in the cloud gets saved on your Mac’s hard drive, presumably for faster access later on. Since there is rarely a need to see such files again and again (otherwise you would have downloaded them and saved manually) these files end up as deadweight on your Mac’s hard drive.
You can improve your Mac’s performance by manually clearing your browser cache, emptying your Downloads folder(s) and clearing Trash folders. Those are useful steps to follow regularly, but in terms of fixing your slowing Mac hard drive that would only be scratching the surface of the problem.
Some of these files get deleted automatically, while others accumulate in multiple hidden folders on your hard drive, slowing your Mac down. Since many of such files are system-generated, Mac users need to be technically proficient enough to know their Mac’s hard drive folder structure and be able to tell apart useful system files from the junk ones.
You don’t have to try finding all the junk files manually clean your Mac hard drive every time your apps freeze and you see the spinning pinwheel. Download free cleaner apps and let it keep your Mac fast for you, every time. They specifically geared towards locating hard-to-find files that do little more than slow down your Mac. Let the app scan your Mac’s hard drive so you can decide which files to clean up with just a few clicks!
What useless files can be stored on disk?
No matter how you use your Mac for your daily tasks, your hard disk is constantly getting cluttered with files like:
- Cache files saved by web browsers
- Duplicate media files
- System and application logs
- Additional system language files
Files like the above are generated automatically with everyday use and are stored within hidden library folders, so it’s hard to keep track of their number, location and of the amount of hard drive space they take up. Even for the most nit-picky Mac users, the task of location and deleting all of the useless files is very time consuming. Besides, cleaning up your Mac hard drive manually after each time you use it is not a very practical solution.
If MacBook Pro laptops take longer to slow down due to being more powerful to begin with, MacBook Air hard drive space is more limited, resulting in higher need for removing junk files on an ongoing basis. Although built for web browsing and keeping files in the cloud, MacBook Air laptops still get clogged up with junk files that are constantly saved “locally”, meaning on your Mac’s hard drive.
