When open Dr. Cleaner on your Mac, you'll see the main window with five options: Junk Files, Big Files, Deplicate Files, App Manager, More Tools. I'll explain what these features do and how to use these features in detail.
To clean junk files is the first reason why a user want to get a Mac cleaner. Dr. Cleaner can scan out all the junk files that are safe to delete, including application caches, application logs, iTunes temperary files, mail caches, files on trash can, browser cache. To clean junk files:
Choose "Junk Files".
After scanning, select files that you don't need.
Click "Remove" on the bottom.
Big files, such as movies, music, could be the culprit for the slow Mac. Dr. Cleaner can help you identify userless big files (that's the files with size larger than 10 MB). After the files are scanned out, you can filter the results based on size, date, name of the files. To avoid mistaken deletion, there is lock feature that allows users to lock important files to white list, which is very thoughtful.
