OmniDiskSweeper is a free app that provides an organized list view of your disk usage. It lists all the folders in descending order according to their size, allowing you to quickly identify which ones are consuming the most space.


GrandPerspective is another free app that displays your disk usage as colorful rectangles. The size of each rectangle represents the size of the corresponding file or folder. By visually analyzing the rectangles, you can easily spot large files or folders that need attention.

Cleaning Up Your Mac

Once you have identified what is taking up space on your Mac, it’s time to declutter! Here are some steps you can take:

  • Delete Unnecessary Files: Remove old documents, downloads, and media files that you no longer need.
  • Empty Trash: Make sure to empty your Trash to permanently delete files from your Mac.

  • Clear Cached Files: Use cleaning apps like CCleaner or CleanMyMac to clear out temporary and cached files.

By regularly decluttering and organizing your Mac, you can maintain optimal performance and prevent storage issues in the future.

In conclusion, understanding what is taking up space on your Mac is crucial for efficient storage management. Whether you use Finder, Disk Utility, or third-party apps, take the time to analyze your disk usage and clean up unnecessary files.
