Storage

EtreCheckPro's storage display is designed to safely show you which folders are most responsible for your storage use. If you are running low on available storage, this display can help you identify which files can be safely deleted or archived to an external drive.

Each directory of your startup disk is shown divided into a pie chart where the sections are individual directories. The size and colour of each pie chart section are relative to the relative size of that directory in its parent directory. Move your mouse pointer over sections of the pie chart to see the size of that directory on disk instead of a percentage of the current directory size. Click on sections of the pie chart to further explore into sub directories. You can use the links in the current path at the top of the window to navigate to previous folders. Use the Reset button to return to the root directory of the startup disk.

Use the Open in Finder button to explore the current directory in the Finder and delete or archive files to external drives.

Note the following:

Clean up

You may be able to reduce the Unknown space by using the Clean up button. This may recover some storage space temporarily. Eventually, however, you may run low on free storage again.
