Removing dots (i.e. full stops, periods) from file names

[pcspeak]

I got tired of replacing the above, so I wrote this.
replace-dots.cmd

@echo off
:: Replace all the dots in a file name.
:: "How.to.milk.a.moo.cow.mp4" becomes "How to milk a moo cow.mp4"

for %%a in (*.avi, *.mp4, *.mkv, *.srt, *.aac, *.mp3) do call :process "%%a"
goto :end

:process
setlocal
set ext=%~x1
set tmp1=%~1
set tmp2=%tmp1:.= %
set tmp3=%tmp2:  = %
if "%ext%"==".avi" set tmp4=%tmp3: avi=.avi%
if "%ext%"==".mp4" set tmp4=%tmp3: mp4=.mp4%
if "%ext%"==".mkv" set tmp4=%tmp3: mkv=.mkv%
if "%ext%"==".srt" set tmp4=%tmp3: srt=.srt%
if "%ext%"==".aac" set tmp4=%tmp3: aac=.aac%
if "%ext%"==".mp3" set tmp4=%tmp3: mp3=.mp3%
ren "%~1" "%tmp4%"
endlocal
goto :eof

:end

Cheers.

Not wanting to dispute simple window batch script posted, it is simple and does what it suppose to, fast and simple.

Just bringing attention to cross platform python, where a simple graphical gui could be used to confirm renaming. Arguments could be files or a directory (files in it will be renamed) or no argument, just double clicking a python file (current directory will be used for renaming).
All with pop up to confirm renaming (only once for all arguments if more arguments).

@pcspeak...

Don't have an issue with dots. Maybe that's a Linux thing. In Windows it is underscores that I'm always tidying up. This will save quite a bit of time...Thanks

Good idea : can you modify it to recurse through folders?

This should work.

Great work, thank you very much - it does work.
I removed the dots from a whole bunch of files in a few seconds.
