怎樣開啟一個"檔案格式無效"的excel文件

當開啟EXCEL文件的時候,警告提示:"檔案格式無效"。表示你的ｆｉｌｅ經已被破壞了，若不能修復這個　ｆｉｌｅ，　是不可能開啟的．

Are you sure you use Excel to open the Excel file?

What I suggest you to do it, copy the file to your local hard disk, and try to open it from the local hard disk rather than A:. it was because, when you open the file, it will also need the working space to temp store, if you use the A: file to open, the temp file also store in the A:, it may be problem to open it...

Good Luck!!
