I'm trying to remove a certain part of a mp3's name.
So if mp3 is "X (2015)" I want it to recognize the "(2" and delete the rest of the name so I can delete it for every year.
Curiously enough, the most difficult part of this problem is to eliminate the space before the left parenthesis. The Batch file below just eliminate the last character of the new name; if the number of spaces before the left paren may be variable, then a different approach must be used.
#echo off
setlocal EnableDelayedExpansion
for /F "delims=" %%a in ('dir /B *(2*.mp3') do (
for /F "delims=(" %%b in ("%%a") do set "name=%%b"
ECHO ren "%%a" "!name:~0,-1!.mp3"
)
Output example:
C:\> dir /B *.mp3
X (2015).mp3
Y (2012).mp3
C:\> test.bat
ren "X (2015).mp3" "X.mp3"
ren "Y (2012).mp3" "Y.mp3"
#ECHO OFF
SETLOCAL
SET "sourcedir=U:\sourcedir\t w o"
FOR /f "delims=" %%a IN (
'dir /b /a-d "%sourcedir%\*(*.mp3" '
) DO (FOR /f "tokens=1delims=(" %%g IN ("%%a") DO ECHO(REN "%sourcedir%\%%a" "%%~g%%~xa"
)
GOTO :EOF
You would need to change the setting of sourcedir to suit your circumstances.
The required REN commands are merely ECHOed for testing purposes. After you've verified that the commands are correct, change ECHO(REN to REN to actually rename the files.
The directory list in /b basic form is processed and the filenames assigned to %%a. The filemask selects only those filenames that contain (
%%a is then partitioned into the part-before and the part after the first ( and the part before assigned to %%g
It's then a matter of stringing the command together.

I have went through a lot of guides for it, but havent found a way to do something similar to lets say turn all files in folder, like these files:
djhwu4s_cat_ruhg29.png
397y_dog_j0929_ej93.png
8yhh_owl.png
into these:
_cat.png
_dog.png
_owl.png
So basically removing everything from file names but a list of predefined strings i am searching for. In example above i would define list as "_cat", "_dog", "_owl". I know that each file will have only one of these variables, and there will be only one file with each of them in folder.
Will appreciate any tips on how to achieve that. Thanks in advance!
edit:
Here is what i came up with (with stuff i can understund) and what seems to be working fine now.
#echo off
setlocal enabledelayedexpansion
set v1=_cat-cat
set v2=_cat-owl
set v3=_cat
set v4=_dog
set v5=_owl
set v6=_horse
FOR /L %%a IN (1,1,6) DO (
rem echo %%a
rem echo !v%%a!
FOR /f %%f in ('dir /b /a:-D *!v%%a!.*') DO (
REN %%f !v%%a!.*
)
FOR /f %%f in ('dir /b /a:-D *!v%%a!_*.*') DO (
REN %%f !v%%a!.*
)
)
rem using two passes of this simpler code i can grasp and understund with dot and with underscore
rem after constructed variables value i make sure cat-cat is not recognised as and renamed to cat
rem no matter if im getting file with that variable as the last string before extension or another underscore
rem Gonna test it in combat now
For some reason this stuff doesnt work with files containing spaces and characters like:
"ab’c efg_dog.png"
FOR /L %%a IN (1,1,36) DO (
FOR /f %%f in ('dir /b /l /a:-D *!v%%a!.*') DO (
REN "%%f" "!v%%a!.*"
)
FOR /f %%f in ('dir /b /l /a:-D *!v%%a!_*.*') DO (
REN "%%f" "!v%%a!.*"
)
)
After further testing i have realised the problem starts with the %%f, and not the REN function as i thought. echo %%f before ren gives just the first part of the name to the first space, hence the REN function cant find the file. In case of "ab’c efg_dog.png" after finding the file with dir, the %%f becomes just "ab’c".
edit: After more tests and experiments and adding those "delims" to the code, the echo now shows proper, full names to be renamed, but it replaces that weird ’ character with ' for the REN command and thats why it still cant find the file to rename.
FOR /L %%a IN (1,1,36) DO (
FOR /f "delims=" %%f in ('dir /b /l /a:-D *!v%%a!.*') DO (
echo %%f
echo REN "%%f" "!v%%a!.*"
)
FOR /f "delims=" %%f in ('dir /b /l /a:-D *!v%%a!_*.*') DO (
echo %%f
echo REN "%%f" "!v%%a!.*"
)
)
#ECHO OFF

For lack of examples, here's a start.
Always verify against a test directory before applying to real data.
Process the list of filenames that match *_*; find those names that do not start _, pick the second string between the delimiters _ and . and rename using that string (in %%y), prefixed by _ and appended with the original extension.
The ren command is simply echoed to the screen for verification. When happy, remove the echo before the ren to actually execute the rename.
I am trying to replace URL encodings (e.g. %20 as a placeholder for a space) with their corresponding ASCII values in all filenames in a Windows folder and its subfolders.
If have a simple .bat file that can accomplish this, but it has limitations:
#echo off
Setlocal enabledelayedexpansion
Set "Pattern0=%%20"
Set "Replace0= "
Set "Pattern1=%%27"
Set "Replace1='"
Set "Pattern2=%%28"
Set "Replace2=("
Set "Pattern3=%%29"
Set "Replace3=)"
Set "Pattern4=%%5B"
Set "Replace4={"
Set "Pattern5=%%5D"
Set "Replace5=}"
For %%# in ("D:\Dropbox\Music\*.mp3") Do (
Set "File=%%~nx#"
Ren "%%#" "!File:%Pattern0%=%Replace0%!"
Ren "%%#" "!File:%Pattern1%=%Replace1%!"
Ren "%%#" "!File:%Pattern2%=%Replace2%!"
Ren "%%#" "!File:%Pattern3%=%Replace3%!"
Ren "%%#" "!File:%Pattern4%=%Replace4%!"
Ren "%%#" "!File:%Pattern5%=%Replace5%!"
)
Pause&Exit
There are two major limitations I'd like to fix:
It only checks the ..\Music\ folder root. I'd like it to look at
files in subdirectories, too.
It exits the For loop as soon as one of the renames are executed
(all %20's replaced first pass, for example, but nothing else).
And surely there is a better way to specify the encodings and their replacements (rather than variable pairs for each), but that's a nice-to-have feature.
These encodings always take the form %XX, where X are hexadecimal values.
To solve directory recursive search, you could use dir /s /b instead
FOR /F "delims=" %%# in ('dir /s /b "D:\Dropbox\Music\*.mp3"') Do (
...
)
Do not rename the file any time, only after all replacements
FOR /F "delims=" %%# in ('dir /s /b "D:\Dropbox\Music\*.mp3"') Do (
set "file=%%~#"
set "file="!File:%%20= !"
set "file="!File:%%28=(!"
...
move "%%~#" "!file!"
)
I'm using move here, because it works with full pathnames, too
To solve problems with exclamation marks in filenames/paths, you need to toggle delayed expansion
setlocal DisableDelayedExpansion
FOR /F "delims=" %%# in ('dir /s /b "D:\Dropbox\Music\*.mp3"') Do (
set "file=%%~#"
setlocal EnableDelayedExpansion
set "file="!File:%%20= !"
set "file="!File:%%28=(!"
...
move "%%~#" "!file!"
endlocal
)
I'm brand new to batch scripting so I appreciate any help. I've seen similar problems here but can't get my move function to work.
I have files with the following format:
19013_01-PG-18-1000_NC_IL2RG_Ex2_F_D01.ab1
19013_01-PG-18-1000_NC_IL2RG_Ex2_R_H01.ab1
I want to make folders with the following format:
01-PG-18-1000_NC_IL2RG_Ex2
And then move all the files that have *01-PG-18-1000_NC* into that folder name.
Here's what I have so far. It's making the folders the way I want, but I can't get the files to move at all. Tried multiple iterations of the move function, but I'm not totally understanding the tokens and how it relates to the files for moving.

You were very close - the echo line should show you how the filename is parsed into %%a..%%f. The parts separated by ++ which is simply a very obvious separator and shows whether there are spaces in any element.
Adding * to the token-list means "everything after the highest-mentioned token number". Then reconstruct the filename from the parts - string together starting at %%a, re-inserting all the underscores.
This should work also:
#ECHO OFF
SETLOCAL
SET "sourcedir="whatever my directory name is"
PUSHD %sourcedir%
FOR /f %%q IN (
'dir /b /a-d "*_*-*-*-*_*_*_*.*"'
) do (

echo ++%%a++%%b++%%c++%%d++%%e++%%f++FROM++%%q++
MD %%b_%%c_%%d_%%e 2>nul
MOVE "%%q" "%%b_%%c_%%d_%%e"
)
)
POPD
GOTO :EOF
In this version, %%q acquires each filename in turn, then "%%q" can be parsed by for /f and the original filename remains unmolested in %%q ready for use in the move statement.

Yes - misread that you wanted to move all files containing - been up gaming all night...
The above batch is in two sections, the first using %%a..%%f and the second incorporating %%q.
The difficulty faced is that move *[pattern]* will move all of the files, as desired BUT for /f...'dir... builds a list of ALL of the matching files that were originally in the directory.
Once the first filename is processed, those other files containing the 01-PG-18-1000_NC will have been moved, so you'll get a "no files found" error on the next 01-PG-18-1000_NC file in the the list for has built.
Sure, it's possible to cruft together some mechanism for ensuring that the pattern 01-PG-18-1000_NC is only processed once, but a simple if exists for the full filename returned by for...%%a... and rebuilt can be used to gate the MD/MOVE commands as the file will no longer exist when the next 01-PG-18-1000_NC is processed (as it's already been moved). So much easier using the %%q method though.
Of course, you could also simply dispose of the error messages instead of installing a gate - but that's probably regarded as being crude.
Also aschipfl's suggestion of adding delims= to the for...%%q... is quite valid if you have separators like Space in your filenames (and costs nothing, regardless)
Oh - and I'd missed the ( in the do part in my initial response - always happens when you don't actually test the code, especially when you're tired.
I have a directory of academic papers that were named using the convention below:
Author1-(Year)-Title.pdf
For example,
Jones-(2011)-XXX.pdf
Smith-(2002)-YYY.pdf
Johnson-(2015)-ZZZ.pdf
I would like to rename them as
(2011)-Jones-XXX.pdf
(2002)-Smith-YYY.pdf
(2015)-Johnson-ZZZ.pdf
That is, to extract the year from the file name and put it in front.
I tried the following code, which did not work
Setlocal enabledelayedexpansion
Set "Year=2013"
Set "Replace="""
For %%a in (*.pdf) Do (
Set "NewName=(%year%)-%%~a"
Ren "%%a" "%NewName%-File:%Year%=%Replace%!"
)
Pause&Exit
In case XXX also contains hyphens I'd suggest using tokens=1,2* to stop parsing the remainder of the file name.
I'd also remove the parentheses, when the year is first place there is no need to further emphasize it.
#Echo off
for /f "tokens=1-2* delims=-()" %%A in (
'Dir /b "*-(*)-*.pdf"'
) do Ren "%%A-(%%B)-%%C" "%%B-%%A-%%C"
Sample output
> dir /b
2002-Smith-YYY.pdf
2011-Jones-XXX.pdf
2015-Johnson-ZZZ.pdf
Not tested
for /f "tokens=1,2,3 delims=-" %%a in ('dir /b "*.pdf"') do (
echo ren "%%a-%%b-%%c" "%%b-%%a-%%c"
)
this will only echo the intended rename command.If it looks ok remove the echo word.
Derived form this SO article - it works:
#ECHO OFF &SETLOCAL ENABLEDELAYEDEXPANSION
FOR %%x IN (*.pdf) DO (
FOR /f "tokens=1-3 delims=-" %%a IN ("%%~x") DO (
SET "Author=%%a"
SET "Year=%%b"
SET "Title=%%c"
ren %%x !Year!-!Author!-!Title!
)
)
Here is a reliable way of doing what you are asking for even if the author part contains - on its own. The title portion may even contain ( and ), but the author part must not. So this is the code:
#echo off
setlocal EnableExtensions DisableDelayedExpansion
rem // Define constants here:
set "_FILES=.\*-(????)-*.pdf" & rem // (basic pattern to match correct files)
set "_REGEX=^[^()][^()]*-([0123456789][0123456789][0123456789][0123456789])-.*\.pdf$" ^
& rem // (precise filter to exclude files violating the demanded pattern)
if not defined _REGEX set "_REGEX=.*" & rem // (avoid trouble with empty filter)
rem // Loop through all matching files:
for /F "eol=: tokens=1,2,* delims=()" %%F in ('
dir /B /A:-D "%_FILES%" ^| findstr /I /R /C:"%_REGEX%"
') do (
rem // Store the extracted file name parts:
set "LEFT=%%F" & set "YEAR=%%G" & set "REST=%%H"
setlocal EnableDelayedExpansion
rem // Reassemble the name and rename the file:
ECHO ren "!LEFT!(!YEAR!)!REST!" "(!YEAR!)-!LEFT!!REST:*-=!"
endlocal
)
endlocal
exit /B
After having verified the correct output, remove the upper-case ECHO command to actually rename files.
I have a bunch of Pdf files with names like so:
Malcolm Gaskill - History.pdf
Manfred B. Steger - Globalization; A Very Short Introduction.pdf
I want to rename them to get rid of everything before the first hyphen so they end up like:
History.pdf
Globalization; A Very Short Introduction.pdf
How do I go about doing this?
Thanks

You would need to change the setting of sourcedir to suit your circumstances.
The required REN commands are merely ECHOed for testing purposes. After you've verified that the commands are correct, change ECHO(REN to REN to actually rename the files.
Not particularly easy for a beginner, since the filenames may contain ; which is a separator like Space
First, perform a dir /b to get all of the required filenames which are applied to %%a using for /f with no delimiters.
Next, tokenise using - into %%b and %%c, then remove leading separators from %%c using tokens=* applying required filename to %%d.
Then mix-and-match to build the required rename command.
