Batch Changing of a File Extension

Using File Explorer, I highlighted a bunch of files with extension
..m4b in a directory. I then opened Windows PowerShell and typed the
command, "rename *.m4b *.mp4" next to the prompt showing the
directory. I got the following message: rename : the term 'rename' is
not recognized as the name of a cmdlet, function, script file, or
operable program. What the heck did I do wrong?

This seems to be the standard utility for this sort of thing........

Nope. Windows Power Shell doesn't recognize ren either.

But regular CMD does.

You are right! I didn't notice that File Manager gives you both the
Open cmd prompt and Open Windows PowerShell options. I suppose I have
to do some research now to learn what PowerShell can do.

I wish I knew. When I tried ren *.m4b *.mb4, I got the message,
ren: Cannot process argument because the value of argument "path" is
not valid. Change the value of the "path" argument and run the
operation again.

However ren *.m4b *mb4 works fine with the command prompt. Do they
want me to repeat the entire path before each of the two arguments
even though PowerShell's top row is PS Path ?

Accept wildcard characters: False --- Oh my.

This is the only command I could get to work. No amount
of double-quoting or single-quoting or mixing the two would work.

The "backtick" character can be used to escape the space in my "user name".
At first I thought the example, was a speck of dirt on my screen, but
no, it was a backtick character strategically placed.

rename-item -path C:\users\user` name\Downloads\test.m4b -newname test.mp4

So that executed successfully, and is... totally useless.

"He shoots... own goal!!!". Nice work Microsoft. How quaint.

I sure got to see lots of different error messages. My screen
is a sea of red ink.

I can see how this is a "direct replacement" for Command Prompt.

And you wonder why young people don't want to take up programming...
