我觉得最大的特点就是：除了可以对某个文件夹下的全部文件（除文件夹和子文件夹下文件）改名外，还可以，任意选择该文件夹下的部分文件，进行批量有规律的修改，当然单个文件的修改就不用说了。
还有就是本软件，除了可以修改文件名，还可以修改文件的扩展名。(I think the biggest feature is: in addition to a folder of all files (except folders and sub folders under the file name), can also choose any part of the file in the folder, batch regular changes, of course a single file is needless to say.
In addition to this software, in addition to the modification of the file name, you can also modify the extension of the file.)
