@echo off

setlocal disableDelayedExpansion

set "root_dir=c:\somewhere"
pushd "%root_dir%"
for %%a in ("* *.png") do (
    setlocal enableDelayedExpansion
    set "f_name=%%~nxa"
    set "cf_name=!f_name: =-!"
    ren "%%~nxa" "!cf_name!"
    endlocal
)
endlocal

Check also this (which in your case will not apply)

The script will be more efficient if the FOR loop uses `"* *"` for the file mask. – dbenham Sep 17 '14 at 18:57

Delayed expansion must be toggled on and off within the loop if any names contain `!`. – dbenham Sep 17 '14 at 18:58

This code snippet will do

cmd /e:on /v:on /c "for %f in ("* *.txt") do (set "n=%~nxf" & set "n=!n: =-!" & ren "%~ff" "!n!" )"

Input: New Text Document.txt

Output: New-Text-Document.txt
