題雖混淆,唯有推理,以下是英文教法,因翻譯中文費時,得張就些了。
=================================================================
1. Click My computer, click to open C: drive.
2. Click Tools at top tool bar then click Folder options.
3. Click View then scroll down to uncheck (不勾選) Hide file extensions of known type.
4. Click OK to execute then minimize the C: window for later use.
5. Go to the problem file and check the extension after the filename. If it isn't
.Doc or simply blank, right click the filename and type a name of your
choice but add .doc (don't forget the period in front of doc) after it.
For example, name it Myfile.doc and enter. The file icon should now return to W for Word document. If so, you can open it as usual with MsOffice.
6. If successful, maximize the C: window, repeat steps 1 to 3 but check (勾
選) the Hide file extensions of known type to prevent future accidents.
7. Click OK then close the C: window.

解說:如復原,因你系統誤改或儲存時出錯弄壞伸延檔名,而電腦是靠此識別各類檔案後對找恰當的程式開啟,如延檔名遺失或錯漏,系統失辨,找不出適合程式作啟動,以致檔案僵化。
又:上法為 XP 路向,如推理錯誤致失敗,要上傳多些資料方可教你。
