有關電腦，我的文件，怎樣加密碼？

winXP內置加密功能，但由NTFS的硬碟格式支援。
檔案右鍵>內容>進階..>加密...便行。

P.S. winXP set加密後只有加密者能開啟或解密。

或

用軟件
e.g(加密金剛銷、壓縮軟件-winrar-winzip...)

I am using MS Word 2002...but I think others version might be almost the same...

With your document opened, go to "Tools" on the menu bar (top) ==> "Protect document", then type any password you like.

P.S.: make sure you remember you password as I don't know the way to crack the file if you happen to forget the password.
