Master Uneraser能回復在硬碟中意外刪除的檔案（或是在垃圾桶中所刪除的檔案）。它是直接連接硬碟在低層和忽視已存在在硬碟的資料，因為它要分析硬碟的可 用空間，利用新增加的硬碟空間來找出刪除的檔案。它並不一定知道Windows是否完全刪除掉檔案，從檔案系統中它只抓取檔案記錄，只要刪除掉檔案釋放出 的可用空間沒有被其他檔案給覆蓋的話，它就能回復剛刪除的檔案。

Master Uneraser can recover accidentally deleted files on your hard drives (even files deleted from Recycle Bin). It has direct access to hard drive on low level and ignores information about existing files on drive, because it analyzes free space of hard drive (where it can find deleted files).
