HOW TO COMPACT MAIL FOLDER
不論您使用Netscape或Microsoft的郵件工具（如Outlook Express，Outlook，Mail），當您把郵件刪移除至已
刪除郵件目錄後，再做「清空」的動作，並不能將郵件真的刪除，只是移除索引值並設成不顯示而已。
例如；您在收件夾內有100封的郵件，它們會全部被放置在名為Inbox的這個檔案內，假設是10MB。如果您將它全部刪除至已刪除郵件目錄後，則Inbox的檔案仍為10MB，Trash檔案則增加10MB。即使您在收件夾與已刪除郵件項目內看不到這些郵件，但它們並不會真的自郵件檔(Inbox及Trash)清除。換言之，如果您從未最適化過您的郵件檔的話，那麼您應該要意識到，您的記憶體可能將會因為無法負荷您的郵件量（即使是已經刪除了）而造成系統不穩定，甚至造成郵件檔毀損而導至遺失。
要將已刪除的郵件真的自郵件檔案中移除，請選擇以下您所使用的郵件工具，參考其操作步驟。此外，因為Microsoft系列的中文版郵件工具將Compact譯為「壓縮」，然而因其所指的Compact並非如我們一般所認識的檔案壓縮，為避免造成誤導，以下的說明皆延用其它類似產品的說明，改譯為「最適化」。

Although you delete mail and empty trash in Outlook Express or Netscape etc., it just delete index information and mark mail not to display, the local mail box (file) size is not change really.
