How to extract the content of the first line of a txt file and use this line content to rename the file? Can you process multiple files at once?

I changed "%*" to "*.txt", but it doesn't work for files with space in the file name. I hope the moderator can improve it.
Also, I still don't understand the meaning of the code. Can the moderator explain it again?
Thanks!

If the file name has spaces, the solution is the same as when the path has spaces, just add quotes.

It needs parameters when running, and it can handle cases with spaces in my test. set /p filename=<%%i is used to read the content of the first line of the text. Several commands are very simple, you can refer to Help and Support and should be able to understand it yourself. You can create a shortcut of this batch processing in the sendto directory, so that you can directly select batch renaming with the mouse.

Today I studied it and basically understood it.
But there are still some doubts and I want to ask the moderator. Is "%*" referring to "*.*"? Are the parameters you mentioned also referring to "*.*"? If I want to modify txt, I can input: "1 *.txt", is my understanding correct?
Also, the usage of "do ( )" in the for statement is something I've seen for the first time (that is, "()" after do). There doesn't seem to be an introduction in Help and Support. Can you introduce its usage?

Please check the CALL /? help. This means all parameters of the batch processing. I think the person upstairs made a mistake because they were not clear about this.
