MacClean also allows you to add folders you want to clean from your Mac directly. Please switch to Custom Folder (4) first and then click Add Files button (5) to add folder (s). Or you can also simply drag any folder on your mac to drop in the scanning area.
The time to scan the files varies based on the size of your files. Please keep patient.
