很有意思的一个小程序，用VC++6编写的，用以查询Windows系统内所有的文件类型扩展名及关联，你只用在输入框输入扩展名的第一个字符，它会在下边的列表框中自动显示匹配项目，你也可以一次性输入完整而且正确的扩展名名称，这样程序会输出对应的文件类型图标-Very interesting, a small program written with VC++6 to query the system for all Windows file types and associated extensions, you are only used in the input box, enter an extension, the first a character, it will list below box automatically displays matching items, you can also enter a one-time extension of a complete and correct name, so the program will output the corresponding file type icon
