How to Find Large Files in macOS (Manually & Automatically)

Are you finding that your Mac is running slow and you aren’t sure why? It could be because you have a lot of large files on your computer. Large files can be a burden for anyone, and they’re even worse on computers. They take up space and not only do we have to worry about the file size but also how it might affect our computer’s performance.

In this post, we’ll show you how to find big/large files on a Mac and how to get rid of them effectively. It’s true that you don’t need a third-party Mac program to do this operation. However, many individuals will find it more convenient and time-efficient to use a Mac Cleaner like CleanMyMac X to locate any large files on their computer and remove them in just a few clicks.

How to Locate Large Files on Your Mac Computer Without Using Third-party App

Open the About This Mac option from the Apple menu.

Select ‘Storage’ from the window.

Find and Delete Large Files on Mac

From there, select the ‘Manage…’ button (from the upper right corner of the window)

Repeat the procedure for the ‘Applications’, ‘iCloud’, ‘Music’, ‘Photo’,… tab on this same window.

Here are the five most common storage management areas that you should monitor on a regular basis:

Downloads Folder

The Downloads folder is one of the most popular places for storing large files. This is because it’s used for all downloads, and if left unchecked, can quickly overflow and cause performance issues with your Mac.

You’ll be able to keep this area under control and delete big files before they become a burden if you do a once-a-month scanning and purging of your downloads folder.

Documents Folder

Documents Folder is a folder that holds and organizes all your documents. It’s located in the macOS at: /Users/<username>/Documents

Another typical location to discover numerous huge files is your documents folder. This is especially true if you have a large number of images, videos, or songs that are natively stored in the region through Adobe After Effects, Premiere Pro, or Final Cut Pro.

Trash Folder

The Trash Folder is a folder on your computer that stores all the files and folders that you delete. When you delete a file or folder, it’s moved to the Trash Folder. You can access the Trash Folder by selecting “Trash” from the Dock.

If you’re running out of disk space, you can clear your Trash Folder to regain space. Select the “Trash” from the Dock and choose “Empty.” If you have any files or folders you want to preserve, move them to a different folder.

Applications Folder

The Applications folder in macOS is a special folder that contains all of the applications that are installed on your computer. What you can do to increase the storage space on your Mac is to remove the app that you no longer use from your computer.

iTunes Folder

iTunes is a digital media player application, which is used to play, download, and organize digital audio and video files on personal computers running the macOS and Windows operating systems. The program is also used to manage Apple’s portable devices, such as the iPhone, iPad, and iPod Touch.

iTunes also stores a lot of cached and system junk data on your computer. This can take up a lot of disk space and slow down your computer. To clean out this data, you can either find and delete it manually or you can use a third-party application like CleanMyMac X.
