How to Find and Delete Large Files on Mac

It’s never a good idea to let your Mac get too full. As well as potentially causing performance issues, it could mean you run out of space when you need it most. To avoid that, you need to delete anything you don’t need and perhaps store some files elsewhere. And in that situation, knowing how to find the largest files on your Mac is going to save you a ton of time.
 

Did you know?


Many big files that eat up disk space are scattered across your Mac, making them hard to find. MacKeeper’s Safe Cleanup feature can locate these files with one quick scan.

  1. Open MacKeeper, and select Safe Cleanup from the left-side menu
  2. Click Scan
  3. Click Clean Junk Files to remove the unneeded files

It’s really that easy, so why not download MacKeeper and give it a try. You get one fix for free, so there’s nothing to lose.


There are a few ways you can find and delete large files from your Mac:

Checking common folders for large files on your Mac

One of the simplest things you can do when trying to find and delete big files from your Mac is to just look in the most likely places for them.
 

Common places for large files on a Mac include:

  • Downloads
  • Documents
  • Applications

You should also check your desktop for files you might have dropped there and forgotten about. And you should empty your Trash regularly. Leaving files in there can easily eat up disk space.

 

If possible, you should also check for large files in other Mac user profiles. It’s possible to delete files from other people’s profiles if you have root privileges, but of course, you probably shouldn’t do that without permission. But if you run several accounts on your Mac, it’s a good idea to log into them and search for large files too.

Using Finder to sort and search your Mac for large files

It’s quite easy to check file sizes on a Mac. When you look at files in Finder, you can easily see how large they are. Just open a folder, and then click at the top of the Size column. Each time you click, it will toggle between sorting small to large and large to small. Either way, you’ll be able to see which files are the biggest, making this a quick, easy way to find some of the largest files on your Mac.

There are a few problems with this, though. For a start, this way of searching your Mac for large files is limited to whatever folder you’re in. But you can look in more places using Finder’s search function. 

 

How to find and delete large files using Mac’s Finder search:
 

1. Open a Finder window, and press Cmd + F. This will get search mode up

2. In the dropdown menu on the left, select File Size, if it’s there. It’s not there, select Other, then find it in the list, and click OK

3. In the dropdown menu after File Size, select Is greater than, then enter a file size that you consider to be large in the field next to it

4. If you’re searching This Mac, you’ll see all files that are larger than the size you entered, no matter where they are on your Mac

Both of these options only deal with files, though. They don’t help you find large folders. That’s a problem because you might have folders full of thousands of tiny files that add up to a large chunk of disk space. But there is a quick way to see how large folders are in Finder.

Should you delete large files from your Mac?

Sometimes, of course, you’ll have big files that you want to keep. In such cases, you don’t want to delete them, but it might be a good idea to move them somewhere else. Think about putting them on an external hard drive or saving them to a cloud service like iCloud.

 

Whatever you decide to do, you can follow the tips in this guide to find the largest files on your Mac as quickly and easily as possible. Add in MacKeeper, and you’ve got yourself a powerful security and optimization tool as well.
