I’m a Mac user and I use it for storing large-sized files. I’m a video special effects specialist and I am responsible for my company’s large video files.
I just heard about the Purgeable storage in macOS Sierra. What is it? Can you tell me more about this Purgeable storage?
Apple is very ingenious. The company and its devices wish to work smart as opposed to working hard. They didn’t make your hard drive space bigger.
What they’ve done is to handle the limited space on your Macintosh with the help of cloud storage. This, in turn, made one part of your storage bar and turned it into a piece called “Purgeable.”
Now, let’s dive more into detail with the said slice of the storage pie.
Purgeable storage actually contains files that your macOS refers to as suited for removal. That’s why it’s called purgeable, it can actually be deleted from your drive without causing any issues.
Purgeable storage is actually related to the Optimized storage feature of your macOS Sierra. If Optimized storage is activated, a lot of files gets transferred to the cloud. Some of them are referred to as optional files.
No one is 100% sure as to which files are considered purgeable. Some guessed that files and system-generated files that have these two criteria are considered purgeable:
Super old files you have not used or opened for a really long time.
Files that are already synced to iCloud. Thus, the original file can be removed on your Mac device since it already has a copy on iCloud.
Purgeable files vary in types. It can be any type out there. It can be movies you watched on iTunes. Or, it can also be language files you have never used before.
The type of language files that your system hasn’t displayed cause you might not need it or might not understand it.
However, what renders these files purgeable and what does it actually mean? The system on your device looks for these files.
It knows that when your Mac is about to run out of disk space and your Optimized Storage is activated, it can automatically delete these files to free your storage of space.
You have the ability to check out the amount of space your Mac can purge in a variety of places:
1 - The first method you can do is to check your native storage tab. You can access this tab by going to the Apple Menu and selecting About This Mac. Then, you go to the tab named Storage.
2 - You can also view it on your Finder’s Status Bar. To display your Status Bar, you should click View and then press Show Status Bar.
3 - The third option is to go to the top menu and click Go. Then, select Computer. Next, right-click on the hard drive. Then, go to getting Info.
4 - The fourth option would be to click View. Then, go to the Options panel. This will activate the Desktop display of hard disks.
5 - The final option would be to ask Siri about how much space you have left on your device.
Actually, you don’t need to do this by yourself. But if you wish to do so, you can move to the next part of this guide.
Purgeable space is there in that whenever your device is running out of space, you will be safe knowing that it will automatically clear up the allocated purgeable space. This will lead to more free space on your Mac.
The best thing to do for you to avoid lifting a finger is to activate your Optimized Storage. In this way, your device will automatically purge the said files.
To do this, go to the About This Mac menu. Next, go to the Storage tab. After which, press Manage. Now, you have the ability to activate a particular option that you wish to be synced to iCloud.
