windows - 重命名cmd中的多个文件(Rename multiple files in cmd)

Question

If I have multiple files in a directory and want to append something to their filenames, but not to the extension, how would I do this?

(如果我在一个目录中有多个文件，并且想要在文件名中附加一些内容，但不希望在扩展名中附加一些内容，我该怎么做？)

I have tried the following, with test files file1.txt and file2.txt :

(我已经尝试了以下测试文件file1.txt和file2.txt ：)

ren *.txt *1.1.txt

This renames the files to file1.1.txt and file2.txt1.1.txt

(这会将文件重命名为file1.1.txt和file2.txt1.1.txt)

I want the files to be file1 1.1.txt and file2 1.1.txt

(我希望文件为file1 1.1.txt和file2 1.1.txt)

Will this be possible from cmd or do I need to have a bat file to do this?

(从cmd可以做到这一点还是我需要一个bat文件来做到这一点？)

What about PowerShell?

(那PowerShell呢？)
