One way to find large files that might be eating up space on your Mac is with a smart folder; it's easy to set one up right from the Finder. To create a smart folder that will find large files on your hard drive, simply follow these directions:
- Open a new Finder window and select File > New Smart Folder.
- In the resulting window, select "Other" from the first drop-down menu (the default selection is "Kind), and search for the key word "size." If you wish this item to remain in the menu, select the "In menu" check box. Select the OK button once you select the "Size" item.
- Select "is greater than" from the next drop-down menu.
- Type in the size that you would like to search for files. I would suggest searching using 1 GB, but you can use any size you wish.
