你好朋友;
不知道你什么系统;
你打开控制面板里面那个文件夹选项;
点击文件夹选项窗口上面的文件类型选项卡;
然后点击下面新建按钮;输入你想创建的那种文件的扩展名;按确定;
然后在“已注册的文件类型”列表里面找到你刚刚建好的这种文件类型;点击文件夹选项窗口右下角那个更改按钮;
你就在弹出的这个对话框里面选一个适合打开这种文件类型的程序;把下面那个始终使用此程序打开此类型的文件复选框打勾;确定就ok了;你说说你什么系统好吗
有一种情况,文件可以关联上,但是点击选择默认程序出现题主的这样提示,就可以采用以下===之间的代码:粘贴进记事本,保存为1111.reg后注入注册表

===================================
你需要知道文件类型,比如.doc 文件要关联word 程序,你只要安装word程序,电脑会自动建立关连!建议你先弄清楚文件类型,再安装响应程序,因为自己建立关联较难,同时需要计算机已经安装有能打开那个文件的程序。
我也遇到过,右键打开方式选择默认程序时也会弹出那个“该文件没有。。。。。。。”
我用360系统急救箱修复好了,报告原因是未知文件打开方式异常和目录盘符等关联项异常。
依次操作,右键点击--打开方式---选择程序----
不知道你要打开的是什么文件,是音乐可以选择千千静听,电影选暴风影音之类(前提是电脑要装了那些软件)
