Removing spaces from a variable in batch

Question

I am writing a file to remove spaces from filenames in a folder and then put the result in a .txt file. I just get a result of \"Echo is on.\" over and over.

Answer 1

Run the following batch in the folder holding the files to be renamed

    @echo off
    setlocal enabledelayedexpansion
    for %%j in (*.*) do (
    set filename=%%~nj
    set filename=!filename=.=_!
    set filename=!filename= =_!
    if not "!filename!"=="%%~nj" ren "%%j" "!filename!%%~xj"
    )

you just need to add the print to txt
