replace characters "_ " and " . " in file names to space with a batch file

replace characters "_ " and " . " in  file names to  space  with a batch file
==========================================================
hi
is there a way  for a .bat file to  search  in  files and folders names to  replace characters "_ " and " . " to  space?
attention=
1-(.) character that separate file names from extention  should be ignored   e.g= my.rar
2-(.) character between  numbers that indicate version  of software should be ignored
example=
windows_media.player_12_v1.23.rar
should be converted to
windows media player 12 v1.23.rar

The "." won't work because it will make it "v1 23 rar" with no extension. BUT! You can do the underscores.

@echo off
echo Enter Filename
set /p name=
set name2=%name:_= %
ren %name% %name2%

That should work.

there are different format of "versioning". If you have consistent names for versions such as the sample, here's an alternative solution done in Python (on windows)

Code: [Select]

import glob,os
os.chdir(os.path.join("C:\\","test"))
for files in glob.glob("*.rar"):  #get rar files
    filename = os.path.splitext(files)
    ext=filename[-1]
    thefile = filename[0]
    if "v" in thefile:  #if there is version, check where the letter "v" is
        ind = thefile.index("v")
        change = thefile[:ind].replace("."," ").replace("_"," ")+thefile[ind:].replace("_","")+ext
    else:
        change = thefile.replace("."," ").replace("_"," ")+ext
    os.rename(files,change) 
output

Code: [Select]

C:\test>dir /B  window*rar
windows_media.player_12.rar
windows_media.player_12_v1.23.rar

C:\test>python test.py

C:\test>dir /B window*rar
windows media player 12 v1.23.rar
windows media player 12.rar




The "." won't work because it will make it "v1 23 rar" with no extension. BUT! You can do the underscores.

it will works with a bit workaround  

Code: [Select]

@echo off & setlocal

call:strip "windows_media.player_12.rar"
call:strip "windows_media.player_12_v1.23.rar"
goto:eof

:strip
set n=%~n1
set a=%n:_v=&set v= v%
set a=%a:.= %
echo %a:_= %%v%%~x1
output:

Code: [Select]

D:\batch>strip
windows media player 12.rar
windows media player 12 v1.23.rar

dear Helpmeh
your scripts needs me to  type a file name to  get started !!
well  i  have 1000 file every  day  and week  and i wanted to  program  scan folder and subfolders for finding and replacing whatever is possible but if i should type !! ok  i could do it with a ready  software called "batch  file renamer 2.71"
but i want to  my  own  software do it and do it automatically and unfortunately  i need batch  codes to  complete my  software
thanks

dear gh0std0g74
thanks for your scripts i  havent worked with  pyton can it support batch  codes?
and put a link for download and try  that
by the way   i dont want to  put address or type any  thing i want double click  on  file and fix file names in current folder and subfolders
thanks

dear Reno
i tried your script and it made a "strip" file but no file has ever been  renamed

Ok...Umm

@echo off
for /f "delims=;" %%A in ('dir /b FOLDERNAME') do (
set a=%%A
set a=%a:_= %
ren %%A %a%
)
that should remove the _ with every file in the same folder as the batch file...not the SHOULD, this is untested.

you don't need batch if you work with Python. Its a programming language more powerful than DOS(cmd.exe+tools).
Just type "Activestate python" in google.

my turn to reply,
i only give example how to strip the file name of unneeded characters. i leave the rest for you to modify the code. hint: use 'for' loop & 'ren' command. search in the forum, there are way too many of this kind of example.

it did'nt work dear  Helpmeh
i tried to  replace FOLDERNAME with anything else but it did'nt work why?
can you  test  it yourself?
thanks

Did you add a full address to the folder (EG. C:\Documents and Settings)? Try adding /s after the /b in my script...that also might fix it...

no it did'nt work dear  Helpmeh
i  tried below scripts  but it could not rename "my_folder" folder to  my folder

@echo off
for /f "delims=;" %%A in ('dir /b/s my_folder') do (
set a=%%A
set a=%a:_= %
ren %%A %a%
)

by  the way.. should i  type  my  folders names one by  one in  batch  file?!!!
there should be other way  to  find them  automatically
thanks

Wait, the FOLDERNAME is the folder for what you want renamed.

Helpmeh
is your last post a question?
or i should wait?

The "." won't work because it will make it "v1 23 rar" with no extension. BUT! You can do the underscores.

You forget that you can isolate the name part of the filename+extension using the FOR variable modifier ~n

Also you need to learn about delayed expansion.

can  you  write  a script? can  you  help  me with  that?
i am  not that professional
