Disadvantages of this method

  • This feature is only available for macOS Sierra.
  • The capability to remove the files from the window is not available for all types of files.

2. Use "Finder" (Available for Any Version of Mac's Operating System)

Difficulty: Medium

The Finder on Mac has a built-in function to locate large files on Mac with the Spotlight search. You can click on the folder or hard drive that you want to search. Just go to the search window, and click on the + option present next to the Save button. You can go to the drop-down menus to choose the File Size and Greater Than choices.  Then type the minimum file size that you need to look for and all of the files over that minimum size will be shown in the next window. At last, you can then easily select the large files that you want to remove.

Disadvantages of this method

  • The Finder only displays the single files over particular file size, not the folders that are full of smaller size files, for examples program installs or Downloads.
  • It is very difficult to choose the particular files to delete as you are not provided a proper display for the exact locations of the files and how important these files might be.

3. Use Terminal (for Advanced Users)

Difficulty: Hard

If you’ll ask experienced Mac users how to find big files on mac, they will suggest using the built-in commands to perform a number of different tasks. These commands typed into the Terminal offer almost unlimited access to maximum files that are saved on the computer. To start, open the Terminal by using the Spotlight shortcut of Spacebar and Command, or simply go to the Utilities folder in the Applications by using the Finder. You can carefully type or copy and paste the below command in Terminal:

sudo find / -type f -size +100000k -exec ls -lh {} \; | awk '{ print $9 ": " $5 }'

When this command is executed, it will show all of the files associated with the files that are equal to or greater than the 100 Megabytes in size. Click Return to perform the command. As you are using the superuser permissions, you will have to confirm the actions by providing the account password. To remove the files, type in this command: rm “path” (add the path of the file you wish to delete).

Disadvantages of this method

  • It is a little hard to perform with tough commands.
