Large and old files: This does not fall under the category of junk per se, but there might be files on your Mac that you have completely forgotten about, which are occupying valuable space on your hard drive.
CleanMyMac finds all the different Trash bins - external drive Trash, Mail Trash, iPhoto Trash, etc., - and empties them at the click of a button. Every time you move an item to Trash, it gets stored within the device or app specific Trash folder, and not actually deleted. Trash: OS X maintains different Trash bins for different apps and storage devices. CleanMyMac deletes unwanted iTunes extras and lets you choose old backups and iOS software updates for removal, helping you reclaim space on your Mac. Over time, the app accumulates junk on your Mac in the form of old iOS device and app backups, old software updates, broken downloads and more.
It helps you keep iOS backups, install iOS software updates and download media from the iTunes Store. ITunes Junk: iTunes is lot more than a typical music management app. CleanMyMac automatically does that for you. Sure, you can manually clean them out individually, but it would take hours to browse through your mailbox searching for attachments and deleting them. But once they are downloaded (using the Mail app), they get saved on your Mac and remain there occupying precious disk space. Mail Attachments: Attachments in emails are often downloaded for one time use.
