我有一個 encfs 加密的資料夾，只需剪切它的子資料夾的內容並將其貼到 encfs 加密的資料夾之外的另一個資料夾中。在執行此操作時，我收到一條錯誤訊息，指出無法刪除子資料夾，因為它不為空。
問題是，每個文件曾是貼到新資料夾中，舊資料夾中沒有留下任何文件，我ls -ll -a在子資料夾中檢查了該文件：
total 8
drwxrwx--- 1 root plugdev 4096 Nov 9 16:19 .
drwxrwx--- 1 root plugdev 4096 Nov 9 16:19 ..
我不知道total 8這裡應該給我哪些資訊。如果我嘗試，sudo ls -ll -a它會說我沒有這樣做的權限。
基本上同樣適用於rm.如果我這樣做rm -rf foldername，它會說該資料夾不為空。如果我這樣做sudo rm -rf foldername，它會說我沒有這樣做的權限。

該資料夾可能是您加密磁碟區的安裝點。輸入mount終端，然後查看加密磁碟機（儘管為空）是否仍安裝到該資料夾中。您可以使用sudo umount /path/to/folder卸載它（可以說是“關閉加密系統”）。一旦該資料夾不再是活動安裝點，您應該能夠刪除該資料夾。
