Using Disk Map is very straight forward. Please follow the steps below:
1. Open the app and when you see the Folder select screen, press the + icon and select a Folder to scan. We recommend you scan your entire Mac hard drive or your 'Users' folder. Then press 'Next'.
2. Wait for the scan to complete and then press the 'Next' Button. The scanning process can take some time, so please let it run.
3. You will now see a visual tree map display of the directory/storage device you have chosen to scan. The larger the rectangle area a file/folder takes up on your tree map, then more disk space it is consuming. You can right click on any folder or file to either remove or compress it (zip).
