系統清理

CleanMyMac X 中的系統垃圾清理功能，可以清理Mac內部和外部驅動器中11種不同類型的垃圾，可以清理Mac系統來獲得最大的性能和釋放自由空間，包括：

用戶緩存文件：應用程序的緩存文件原本是用來加快開啟時間的，但最終堆積過多將導致功能失常或總體性能下降。

系統緩存文件：系統應用程序產生並保存大量的文件，並最終導致開機時間更長，總體性能下降甚至優勢功能失常。

用戶日誌文件：應用程序的活動會不斷地被捕捉到很多日誌文件中，這些文件在經過一段時間的堆積之後會佔用大量的磁盤空間，但它們的用處並不大，老日誌尤其如此。

系統日誌文件：系統應用程序和服務的活動會被捕捉到許多的日誌中，這些日誌文件可能僅對程序調試有幫助，可以毫不猶豫被刪除。

iPhoto垃圾清理

CleanMyMac X 的iPhoto垃圾清理功能會瀏覽您的iPhoto圖片庫，找到那些經過裁剪、調整大小、旋轉或者其他編輯之後不再需要的但仍被iPhoto保存的原始圖片副本。這些副本是隱藏的，但是它們卻極大的增加了圖片庫的大小。

郵件附件清理

郵件附件清理功能可以保證在收件箱中原始附件的安全性的基礎上，清理郵件下載和附件的本地副本，回收大量的磁盤空間。在默認情況下，當您打開或者查看新的郵件附件時，應用程序將將其副本存儲到磁盤上直到您刪除相關的電子郵件。在這期間，累積的郵件附件可能達到GB或者更多，特別是當你郵件附件中包含很多圖片、PDF或者演示文件的時候。

iTunes垃圾清理

iTunes會積累大量的垃圾，但是很多人都不知道如何徹底清理它，手動清理並不能完成清理乾淨，現在CleanMyMac X自動清理清理過時的iOS設備備份、軟件更新和其它iTunes支持數據。

廢紙簍清理

CleanMyMac X 的廢紙簍清理功能可以幫助清空您所有的內置和外置驅動器上包括iPhoto、Aperture和郵件在內的所有系統廢紙簍文件夾，不是所有人都知道，在我們的電腦裡出了啟動磁盤的廢紙簍文件夾外，還存在更多廢紙簍文件夾。每個分區和每個外置驅動器都有自己的隱藏的廢紙簍文件夾，而之前從這些地方刪除的項目都保留在相應的廢紙簍文件夾裡面。

大舊型文件清理

CleanMyMac的大舊文件清理模塊會幫您定位、檢查和移除您幾個月沒有打開過並且不再需要的大型文件和文件夾，這樣可以節省更多的磁盤空間。
