        當程式需要建立一種新的檔案格式，往往有這樣一個需求：在檔案清單顯示的時候顯示自己想要的圖示，并且輕按兩下此檔案就會使用指定的程式以指定的指令打開——就像 word，excel 那樣。

        這種情況是通過系統資料庫的設定來實作的，目前我還沒了解實踐指定程式打開，先說修改圖示的方法。以下僅限描述修改位置，可以用不同語言程式通過不同方式程式設計實作。

        1. 在 HKEY_CLASSES_ROOT 分支上增加一個以 “.” 開頭的擴充名的項，如 “.tzr”，設定一個值項：預設，REG_SZ，tzr_file。

        2. 在 HKEY_CLASSES_ROOT 分支上增加一個 “tzr_file” 項，增加新子項 “DefaultIcon”，設定：預設，REG_SZ，”c:\program files\tzrprogram\tzr.ico”

        是的，就這麼簡單！
