共享文件word / excel /ppt 被用戶自己鎖定無法編輯，但用戶嘗試過關閉所有文件和重啓過系統，依然無法編輯。
搜到解決方法：
Just in case someone looking for a solution to this for a Windows based system or NAS:
There is a built-in function in Windows that show you what files on the local computer are open/locked by remote computer (which has the file open throught a file share):
1. Select "Manage Computer " (Open "Computer Management")
2. Click "Share Folders"
3. choose "Open Files"
There you can even close the file forcefully.
首先最好讓鎖定的用戶登出所有設備（最好關機），如圖所示，在Windows 文件共享服務器打開計算機管理，
打開“共享文件夾”——“共用階段”和“打開的文件” 這里找到鎖定的用戶，
清除所有Sessions 和 該用戶打開的文件。
然后應該就可以了。（另外有可能文件屬性被修改為只讀，還需要更改該文件屬性去掉“只讀”）
