What is the Mac swapfile? Is it important? Can you delete it? We’ll walk you through this mysterious Mac file and what you can do about it.
If you’ve even run out of disk space on your Mac, you’ve probably sat and taken some time to look and see what’s eating up all this space (pro tip: it’s easy to forget how many files you move to the Mac Trash folder; the first thing you should do when you run out of space is right-click on the Trash icon on the dock and select Empty Trash).

You might have run across something called swap, or a swapfile. It can be difficult to understand just what these files are, and whether you can manage to do without them, especially since they seem to just sit there and take up space; sometimes they take up quite a lot of space indeed.
What is the Mac swapfile?
Before we delve into what the swapfile is, we have to talk about swapping in the context of how your computer works. When you run a program on your Mac, it gets loaded into your memory (RAM). You have a much smaller amount of RAM than you do storage on your SSD.
Occasionally, if you’re doing something that requires a lot of memory, you’ll come up against some of the limits that come with having limited RAM. Enter paging. Paging is what we call using your storage drive as memory. It’s all done automatically by your computer, so you never tend to notice when it happens. While the terms originally meant something different, these days paging and swapping are largely synonymous.
When you write something to your disk, it isn’t always written in contiguous stretches of storage; instead it might be written in a number of places, wherever your Mac (PCs do this, too) finds an open spot.
In order for swapping to work, your Mac usually needs one of those contiguous stretches, which can be difficult to find on a drive as it increasingly fills up with data. To mitigate this, OS X will generate a number of these swapfiles so that it can write (or page, or swap) to them whenever it needs them.

How many files appear depend on a number of factors: how much and how often the Mac has needed to swap to your storage drive (which itself will depend on how much memory you have and how many programs you use that may have memory leaks). For reference, the above swapfiles were generated on a Macbook Pro with 16GB of RAM; it’s gone around ten days since it was last rebooted.
Can you delete Mac swapfiles?

Chances are good that on a new Mac you’re unlikely to run into issues where your swap is seriously impacting how much free space you have. Should you keep running into an issue, however, take a look at the apps you run on a regular basis, and try playing around with them one at a time. You might find that one app has a memory leak, and by rebooting after use or finding an alternative app, you can avoid the big swapfile issue altogether!
