I actually had two additional libraries on my iMac, and I have no idea why. This can be caused by apps that were deleted long ago, or even duplicates. It had come over from several backups and they were already backed up to an external, leaving no need them to take up space. You can think of DaisyDisk as a pack of hounds with one job — sniffing out large files on your hard drive and drawing your attention to them.
And of course it can help you clean them up as well. Service files and app remnants can eat up terrible amounts of disk space. Sometimes I download apps with every intention of using them, and then I never do. This is where I end up deleting them. If I ever need them again, I can just re-install. AppCleaner also lets you pick and choose what files you delete inside an app. That being said, AppCleaner does an excellent job of helping you clean up unused apps that are hogging unnecessary storage.
And whenever you add another piece to your workflow, it seems the duplicates always love to come back in droves. If you suspect you have duplicate photos floating around in your library, there are tons of apps available to help you clean them up. One of my favorites is PhotoSweeper. Not only can it scan your library for exact matches, you have tons of options for customizing your photo triaging.
For example, I can search for only photos of the exact same file type great for photographers who only want to search for RAW files , or only files of the exact same size. Instead, you can stream them using iTunes in the Cloud. As you can see in the screenshot above, I have a cloud icon next to all of my movies. Each browser limits its cache to a maximum amount of disk space, anyway. This will pull up a folder that has a ton of folders in it, which you can select and delete manually if you choose. You can clean up temporary files easier, and much safer, by using CleanMyMac.
Just open it up and run through a scan, and then go into the System Junk section to identify all of the cache files and other things that you can clean up. The thing about temporary files, of course, is that most of them are going to come back after you use your Mac for a while.
So deleting temporary files is great, but only works for a while. You can then delete these space hogs to free up space.
If you care about these files, you may want to move them to external media — for example, if you have large video files, you may want to store them on an external hard drive rather than on your Mac. Mac applications come with language files for every language they support. However, you probably just use a single language on your Mac, so those language files are just using hundreds of megabytes of space for no good reason.
You can change the Mail settings to not download attachments automatically to save space, or run a cleanup tool to get rid of them. You can run a scan, head to Mail Attachments, and see all of the attachments that can be deleted.
Click Clean, and your hard drive will be free of them. And those folders sit there looking innocuous but taking up tons of space on your drive. Once you are there, you can go through the new settings and enable the ones that make sense to you. For example, you can delete downloaded. Every second your Mac is on, the macOS creates and piles up system files — logs, for example.

At some point, the system needs these files, but they quickly become outdated and just sit there wasting your disk space. And guess what, they are in the Other Mac storage category, too.
Other Storage on Mac eats up your Disk Space? Here are 6 tricks
These files are mostly temporary but they never actually go away unless you do something about it. So where do you even look for system files? In this folder you will find your applications and some searching will reveal a lot of space being taken up. You could delete these manually but a much safer and faster method is to use a specialist cleaning app like CleanMyMac X.
Cache files are not just another invisible storage hog. They are often one of the worst offenders, often taking up gigabytes of precious space. The three main types cache are — browser, user, and system. Cache files are meant to help your system work faster, but over time they get bigger and bigger, eventually slowing your system down.
If you already cleaned out system files from step 2, congratulations, in doing so you also cleared out your cache files. This will clear all the cache files on your Mac and considerably reduce Other storage on your Mac.

While apps are, unsurprisingly, categorized as Apps on the Storage bar, their add-ons are under the Other storage category. Still, every bit counts.
