　　大家都知道电脑文件都有一个格式，比如JPG、MP3等等格式，每个格式都代表不一样文件类型，那么我们要如何批量更改文件类型的后缀名呢？下面就和小编一起来看看有什么解决方法吧。

　　Win7批量更改文件后缀名的方法

　　1、查看或显示文件后缀名，方法一：右键选择文件“属性”，即可查看文件的类型。

　　2、点击左下角的“开始键-控制面板-文件夹选项”，然后点击“查看”，

　　找到“隐藏已知文件夹类型的扩展名”取消勾选，点击应用，就可以直接显示文件的后缀名。

　　3、修改文件后缀名，直接选择文件，右键选择“重命名”或者按住键盘“F2”键修改。

　　4、假如要把GIF文件批量修改成为JPG文件，在需要修改的文件夹中，右键新建一个“文本文档”。

　　打开文本文档后在里面输入“ren（空格）*.gif（空格）*.jpg”的内容，设置好之后保存文件，

　　同时把这个文本你文档改成“.bat”后缀名的文件，设置好之后点击运行刚刚那个bat文件，就可以看到GIF文件全变成JPG文件了。

　　5、文件夹里有不同类型的文件，需要统一批量修改后缀名，在该文件中新建一个文本文档，

　　打开文本文档，输入“ren（空格）*.*（空格）*.gif”，设置好之后保存文件，

　　同时把这个文本文档改成“.bat”后缀名的文件，然后点击运行该文件，就可以全部修改后缀名了。

　　6、如果批量修改不同路径的文件名后缀，首先复制文件夹的路径，在任意的文件夹上新建一个文本文档，

　　打开文档，输入“cd（空格）文件的路径ren*.gif（空格）*.jpg”，设置好之后保存文件，

　　把文本文安定改成“.bat”后缀名的文件，然后运行文件即可完成。
