If you're searching for how to find large files on Mac , you're probably running out of storage and wondering what's taking up so much space. Over time, large files like old videos, forgotten downloads, backups, and unused apps quietly pile up, slowing down your Mac and leaving you with constant "disk almost full" warnings.
The good news is that macOS provides built-in ways to locate large files—but they often require manual sorting, multiple clicks, and a lot of patience. For many users, it's easy to miss hidden files or accidentally delete something important.
In this guide, we'll show you how to find where large files are on Mac using Finder and macOS storage tools, and then introduce Cleamio, a smarter and faster solution that automatically scans your Mac, highlights the largest files, and lets you safely remove what you don't need. If you want to free up space without the stress, you're in the right place.
Before learning how to find large files on your Mac, it helps to understand what usually fills up storage so quickly.
Large files often include:
These files are often forgotten and sit unnoticed in folders for months—or even years.
When large files consume most of your disk space, macOS has less room to operate efficiently. This can cause slower performance, longer app launch times, failed updates, and system lag. Clearing large files is one of the fastest ways to restore speed.
macOS includes basic tools that can help you locate large files without installing extra software.
Finder allows you to search files by size:
This method helps you identify large files across your Mac, though it may take time to review results manually.
Go to Apple menu > About This Mac > Storage > Manage.
Here, macOS categorizes files like Applications, Documents, and Media, making it easier to spot which categories are taking up the most space. While helpful, this view doesn't always show detailed file locations or duplicates.
Manual methods work, but they aren't always efficient—especially for users with years of accumulated data.
Built-in tools don't automatically:
You may also spend a lot of time switching between folders and comparing file sizes.
Without clear guidance, it's easy to delete files you still need. That's why many users prefer a tool that clearly separates safe-to-delete files from important system data.
