How to remove spaces from file names (in bulk)

Question

Here is a script that can efficiently bulk rename files, stripping all spaces from the name.

:renameNoSpace  [/R]  [FolderPath]
@echo off
setlocal disableDelayedExpansion
if /i "%~1"=="/R" (
  set "forOption=%~1 %2"
  set "inPath="
) else (
  set "forOption="
  if "%~1" neq "" (set "inPath=%~1\") else set "inPath="
)
for %forOption% %%F in ("%inPath%* *") do (
  if /i "%~f0" neq "%%~fF" (
    set "folder=%%~dpF"
    set "file=%%~nxF"
    setlocal enableDelayedExpansion
    echo ren "!folder!!file!" "!file: =!"
    ren "!folder!!file!" "!file: =!"
    endlocal
  )
)

Assume the script is called renameNoSpace.bat

renameNoSpace : (no arguments) Renames files in the current directory

renameNoSpace /R : Renames files in the folder tree rooted at the current directory

renameNoSpace myFolder : Renames files in the “myFolder” directory found in the current directory.

renameNoSpace "c:\my folder\" : Renames files in the specified path. Quotes are used because path contains a space.

renameNoSpace /R c:\ : Renames all files on the C: drive.
