方法一

name
重新命名一个文件、目录、或文件夹。
语法：
name oldpathname as newpathname 

Name语句重新命名文件并将其移动到一个不同的目录或文件夹中。如有必要，Name可跨驱动器移动文件。但当newpathname和oldpathname都在相同的驱动器中时，只能重新命名已经存在的目录或文件夹。Name不能创建新文件、目录或文件夹。在一个已打开的文件上使用Name，将会产生错误。必须在改变名称之前，先关闭打开的文件。Name参数不能包括多字符(*)和单字符(?)的通配符。

示例本示例使用Name语句来更改文件的名称。示例中假设所有使用到的目录或文件夹都已存在。在Macintosh中，默认驱动器名称是C, imOldName,NewNameOldName="OLDFILE":NewName="NEWFILE"注释：定义文件名。NameOldNameAsNewName注释：更改文件名。OldName="C:\MYDIR\OLDFILE":NewName="C:\YOURDIR\NEWFILE"NameOldNameAsNewName注释：更改文件名，并移动文件。
