I am trying to rename a lot of files. I only want to change the extention from ".pdf.OCR.pdf" to ".pdf"
So far I got the following code
rem for /r myPDFfolder %%i in (*.pdf.OCR.pdf) do ren "%%i" "%%~ni.pdf"
But it does not appear to work with the extension that has multiple dots -- what am I doing wrong?
Extension is the part of file name after the last dot.
Use string replacement to strip the unneeded part:
setlocal enableDelayedExpansion
for /f "eol=* delims=" %%i in ('dir /s /b "r:\*.pdf.OCR.pdf"') do (
set "name=%%~nxi"
ren "%%i" "!name:.pdf.OCR=!"
)
P.S. Parsing of dir is used to make the code more robust in case a different text is stripped which might have changed the sorting order and cause for to process the file twice or more times.
There is no need for a batch file. A moderate length one liner from the command prompt can do the trick.
If you know for a fact that all files that match *.pdf.ocr.pdf have this exact case: .pdf.OCR.pdf, then you can use the following from the command line:
for /r "myPDFfolder" %F in (.) do #ren "%F\*.pdf.ocr.pdf" *O&ren "%F\*.pdf.o" *f
The first rename removes the trailing .pdf, and the second removes the .OCR. The above works because *O in the target mask preserves everything in the original file name through the last occurrence of upper-case O, and *f preserves through the last occurrence of lower-case f. Note that the characters in the source mask are not case sensitive. You can read more about how this works at How does the Windows RENAME command interpret wildcards?
If the case of .pdf.ocr.pdf can vary, then the above will fail miserably. But there is still a one liner that works from the command line:
for /r "myPDFfolder" %F in (*.pdf.ocr.pdf) do #for %G in ("%~nF") do #ren "%F" "%~nG"
%~nF lops off the last .pdf, and %~nG lops off the .OCR, which leaves the desired extension of .pdf.
You should not have to worry about a file being renamed twice because the result after the rename will not match *.pdf.ocr.pdf unless the original file looked like *.pdf.ocr.pdf.ocr.pdf.
If you think you might want to frequently rename files with complex patterns in the future, then you should look into JREN.BAT - a regular expression renaming utility. It is pure script (hybrid JScript/batch) that runs natively on any Windows machine from XP onward. Full documentation is embedded within the script.
Assuming JREPL.BAT is in a folder that is listed within your PATH, then the following simple command will work from the command line, only renaming files that match the case in the search string:
jren "(\.pdf)\.OCR\.pdf$" $1 /s /p "myPDFfolder"
If you want to ignore case when matching, but want to force the extension to be lower case, then:
jren "\.pdf\.ocr\.pdf$" ".pdf" /i /s /p "myPDFfolder"
Alternative solution, without delayed expansion (remove ECHO to actually rename any files):
#echo off
rem iterate over all matching files:
for /F "delims=" %%A in (
'dir /S /B /A:-D "myPDFfolder\*.pdf.OCR.pdf"'
) do (
rem "%%~nA" removes last ".pdf"
for /F %%B in ("%%~nA") do (
rem "%%~nB" removes ".OCR" part
for /F %%C in ("%%~nB") do (
rem "%%~nC" removes remaining ".pdf"
ECHO ren "%%~fA" "%%~nC.pdf"
) & rem next %%C
) & rem next %%B
) & rem next %%A
NOTE: The directory tree is enumerated before for iterates through it because otherwise, some items might be skipped or tried to be renamed twice (see this post concerning that issue).

I have a flawlessly working batch file when dealing with filenames using common English alphabet characters, but it fails miserably for some using non English ones.
Batch file:
Rem Command to move all files that have "2013" in the file name to a specified directory.
for /F "eol=: delims=" %F in ('dir /b|find "2013"') do (
move /Y "%F" "M:\Hebrew\_Movies - Hebrew 2011-2015" )
Output:
M:\Hebrew Unsorted>move /Y "2013 ??? ???" "M:\Hebrew\_Movies - Hebrew 2011-2015"
The filename, directory name, or volume label syntax is incorrect.
Observation:
The command does not specificly move the specified file in the %F loop, but 2013 ??? ???, which means that many more files will be moved as well.
This is my first attempt at a solution, expecting that the ~s should report the shortname for the file.
#ECHO OFF
SETLOCAL
dir /x /a-d "*.mp3"
FOR /f "delims=" %%b IN ('dir /b /a-d "*.mp3" ') DO (
ECHO "%%~sb" short FOR "%%b"
)
It seemed to work, until I looked closely:
Note that the second filename is reported as the shortname for the second unicode filename.
So, I stashed that away as a trap, no doubt of interest to #jeb (could be well-known, but I've not tripped over it before)
and then I tried this, which seems to work:
#ECHO OFF
SETLOCAL
FOR /f "tokens=4delims= " %%b IN ('dir /x /a-d /-c "*.mp3"*^|findstr /v /b /c:" " ') DO (
ECHO "%%~sb" short FOR "%%b"
)
Here, the dir list is created with the /x option to show the shortname. /-c removes thousands separators from the filesize and /a-d suppresses directorynames. The output of dir is piped (the pipe is escaped, as required) to findstr which looks for lines /v not-including /b at the beginning of the line /c:" " a space, which excludes the superfluous report lines.
The resultant lines will have in the 4th token either the shortname in the case of non-8.3 filenames, or the 8.3 filename. I use HH:MM for time, obviously, so those who use Spaceam/pm (as distinct from am/pm with no space) will need to choose the 5th token.
so in one other recent question i needed to find a solution to bulk renaming files by adding .ab into the filename. I succeeded in doing that, but now i face a different problem. Every time i run the batch file, it appends .ab to all the files even those, already renamed. I tried fixing the problem in the following way, which doesn't work.
rem #echo off
FOR /R "C:\Users\" %%G in (*.txt) DO (
%%G|findstr /i /L ".ab">nul
IF errorlevel 1 (
REN "%%G" "%%~nG.ab.txt"
) ELSE (
skip %%G
)
)
pause
Essentially i need to check if the file name already contains ".ab" in its name and then either skip or add .ab depending on the result. I would appreciate any help.
Use a For /F loop, instead of For /R. In addition, instead of using the Dir command with its /S option, (which will output items ending with .txt*), use Where with its /R option instead, (which will output items ending with .txt).
Single line batch-file example, (excludes those basenames ending with, not containing, .ab):
#For /F "Delims=" %%G In ('^""%__AppDir__%where.exe" /R "C:\Users" "*.txt" 2^>NUL^|"%__AppDir__%findstr.exe" /IV "\.ab\.txt$"^"')Do #Ren "%%G" "%%~nG.ab%%~xG"
Don't forget to change C:\Users and/or both instances of .txt and ab as/if necessary.
I need a windows batch file to create a folder based on part of a file name (the part before an underscore) and move any files that start with the folder name into the folder.
I'm not familiar with windows batch files. I've googled and tinkered a solution which works except that I cannot substring the file name at the underscore.
(Yes there are a few similar threads but nothing I could use to exactly answer my question)
FWIW my unsuccessful solution:
#ECHO OFF
setlocal enabledelayedexpansion
SETLOCAL
SET "sourcedir=C:\Development\test"
PUSHD %sourcedir%
FOR /f "tokens=1*" %%a IN (
'dir /b /a-d "TTT*_*.*"'
) DO (
ECHO MD NEED FILE NAME BEFORE UNDERSCORE HERE
ECHO MOVE "%%a" .\NEED FILE NAME BEFORE UNDERSCORE HERE\
)
(Ideally I'd remove the leading 'TTT' from files too but if necessary can create the files without this.)
Try this batch file code:
#echo off
setlocal EnableExtensions DisableDelayedExpansion
set "SourceDir=C:\Development\test"
set "DestDir=C:\Development\test"
for /F "eol=| delims=" %%A in ('dir /B /A-D-H "%SourceDir%\TTT*_*" 2^>nul') do (
for /F "eol=| tokens=1 delims=_" %%B in ("%%~nA") do (
md "%DestDir%\%%B" 2>nul
move /Y "%SourceDir%\%%A" "%DestDir%\%%B\"
)
)
endlocal
The first FOR executes in a separate command process started with cmd.exe /C in background the command line:
dir /B /A-D-H "C:\Development\test\TTT*_*" 2>nul
DIR searches in specified directory for
just non-hidden files because of /A-D-H (attribute not directory and not hidden)
matching the wildcard pattern TTT*_* which could be also just *_*
and outputs to handle STDOUT in bare format because of /B just the file names with file extension, but without file path.
The error message output by DIR to handle STDERR if the specified directory does not exist at all or there is no file matching the pattern is suppressed by redirecting it with 2>nul to device NUL.
Read also the Microsoft documentation about Using Command Redirection Operators for an explanation of 2>nul. The redirection operator > must be escaped with caret character ^ on FOR command line to be interpreted as literal character when Windows command interpreter processes this command line before executing command FOR which executes the embedded dir command line with using a separate command process started in background.
FOR captures everything written to STDOUT of started command process and processes the captured output line by line.
FOR ignores by default all empty lines (do not occur here) and all lines starting with a semicolon. A file name could begin with a semicolon. For that reason option eol=| is used to redefine end of line character to vertical bar which a file name can't contain, see Microsoft documentation Naming Files, Paths, and Namespaces. In this case on using TTT*_* as wildcard pattern it is not possible that a file name starts with a semicolon, but it would be possible on usage of *_* as wildcard pattern.
FOR would split up also each line into substrings (tokens) using space/tab as delimiters and would assign just the first space/tab separated string to specified loop variable A. This splitting behavior is not wanted here as file names can contain one or more space characters. Therefore the option delims= is used to define an empty list of delimiters which disables line splitting completely and results in assigning entire file name with extension to loop variable A.
The inner FOR processes just the file name (without extension) as string. This time the file name is split up using the underscore as delimiter because of delims=_ with assigning just first underscore delimited string to loop variable B because of tokens=1. Well, tokens=1 is the default on using for /F and so this option string could be removed from code.
So the outer FOR assigns to A for example TTTxy_test & example!.txt and the inner FOR processes TTTxy_test & example! and assigns to B the string TTTxy.
The command MD creates in set destination directory a subdirectory for example with name TTTxy. An error message is output also on directory already existing. This error message is suppressed by redirecting it to device NUL.
Then the file is moved from source to perhaps just created subdirectory in destination directory with overwriting an existing file with same name in target directory of the file.
The inner FOR loop could be optimized away when there are never files starting with an underscore or which have more than one underscore after first part of file name up to first underscore.
#echo off
setlocal EnableExtensions DisableDelayedExpansion
set "SourceDir=C:\Development\test"
set "DestDir=C:\Development\test"
for /F "eol=| tokens=1* delims=_" %%A in ('dir /B /A-D-H "%SourceDir%\TTT*_*" 2^>nul') do (
md "%DestDir%\%%A" 2>nul
move /Y "%SourceDir%\%%A_%%B" "%DestDir%\%%A\"
)
endlocal
Option tokens=1* results in assigning first underscore delimited part of file name to loop variable A and rest of file name to next loop variable B according to ASCII table without further splitting up on underscores.
But please take into account that the optimized version does not work for file names like
_TTTxy_test & example!.txt ... underscore at beginning (ignored by pattern), or
TTTxy__test & example!.txt ... more than one underscore after first part.
The optimized version can be further optimized to a single command line:
#for /F "eol=| tokens=1* delims=_" %%A in ('dir /B /A-D-H "C:\Development\test\TTT*_*" 2^>nul') do #md "C:\Development\test\%%A" 2>nul & move /Y "C:\Development\test\%%A_%%B" "C:\Development\test\%%A\"
Well, the not optimized version could be also written as even longer single command line:
#for /F "eol=| delims=" %%A in ('dir /B /A-D-H "C:\Development\test\TTT*_*" 2^>nul') do #for /F "eol=| tokens=1 delims=_" %%B in ("%%~nA") do #md "C:\Development\test\%%B" 2>nul & move /Y "C:\Development\test\%%A" "C:\Development\test\%%B\"
See also Single line with multiple commands using Windows batch file for an explanation of operator &.
For additionally removing TTT from file name on moving the file the first batch code is modified with using two additional commands SET and CALL:
#echo off
setlocal EnableExtensions DisableDelayedExpansion
set "SourceDir=C:\Development\test"
set "DestDir=C:\Development\test"
for /F "eol=| delims=" %%A in ('dir /B /A-D-H "%SourceDir%\TTT*_*" 2^>nul') do (
for /F "eol=| tokens=1 delims=_" %%B in ("%%~nA") do (
md "%DestDir%\%%B" 2>nul
set "FileName=%%A"
call move /Y "%SourceDir%\%%A" "%DestDir%\%%B\%%FileName:~3%%"
)
)
endlocal
The file name is assigned to an environment variable FileName. The value of this environment variable cannot be referenced with just using %FileName% because of all references of environment variable values using percent signs are substituted by Windows command processor in entire command block starting with first ( and ending with matching ) before FOR is executed at all. Delayed expansion is usually used in such cases, but that would result here in file names containing one or more exclamation marks would not be corrected processed by the batch file.
The solution is using %% on both sides of FileName environment variable reference instead of % and force a double parsing of the command line by using command CALL.
For understanding the used commands and how they work, open a command prompt window, execute there the following commands, and read entirely all help pages displayed for each command very carefully.
call /?
dir /?
echo /?
endlocal /?
for /?
md /?
move /?
set /?
setlocal /?
It is really very simple:
#echo off
for /f "tokens=1-2 delims=_" %%i in ('dir /b /a-d "TTT*_*"') do (
if not exist "%%i" mkdir "%%i"
move "%%i_%%j" "%%i\%%j"
)
We split by _ into 2 tokens, %%i everything before _ and %%j everything after.
We simply create folder (if it does not exist) then move the file with only the name after the _ into the new folder.
So as an example file TTT123_File1.txt will create a folder called TTT123 and place the file into it but rename it as File1.txt
You might consider using Tcl/Tk. Tcl/Tk is an open source script language. You can call it as a stand-alone or execute it from a windows batch file. You will need to install it first if you don't have it yet.
The following Tcl script does what you want:
cd "C:/Development/test"
# glob is a tcl command to list all functions that match the requirements
set files [glob TTT*_*]
foreach f $files {
# use the underscore as a separator to split f and store the parts in dir and fnew
lassign [split $f "_"] dir fnew
if {![file exist $dir]} {
file mkdir $dir
}
file rename $f [file join $dir $fnew]
}
In my opinion, this is a very readable script, even if you don't know tcl.
You can call this script from a batch file as:
tclsh script.tcl
if you have saved the script as script.tcl
I have several .csv files in one folder. They are saved automatically but with spaces and execution date and time (in seconds) with amount of containing lines.
So far I was not able to run my powershell script with files containing spaces. So I tried to rename filenames using batch. so far nothing is working fine. Either in cmd-line or with a batch file.
Trying to loop in folder to find .csv is working but defining a string and then substring parts of the file not.
for %%i in ('dir *.csv /b /s') do set string = %%~ni
set substr=!string:~20,25!
echo !substr!
I tried first to use % instead of ! but didn't worked as well. Tried to use pipes for the loop as well, didn't worked.
So far my output is just
!string:~20,25!
My output has to be just the "real" filename of the report without anything else before or after it.
For example, do with that path and filename
C:\Users\Username\CSV_Files\Reportoutput Report_2017 2018-01-09T07_10_33.1924R.csv
this
C:\Users\Username\CSV_Files\Report_2017.csv
When I'm able to extract just the filename without any spaces or leading chars like "Reportoutput" (which is always the same) or starting time of report or containing lines in the report I could use that string and combine it with the path where files are saved.
Any ideas? Why is my "substring" not working at all? Do I miss some action? Some code?
I'm using windows.
Based on the file name structure you've presented and looping in one folder, (the current directory), as stated and used in your example code:
#Echo Off
For %%A In ("* * *.csv"
) Do For /F "Tokens=2" %%B In ("%%~nA") Do Ren "%%~A" "%%B%%~xA"
If you wanted to check inside subfolders of the currect directory then change it to this:
#Echo Off
For /R %%A In ("* * *.csv"
) Do For /F "Tokens=2" %%B In ("%%~nA") Do Ren "%%~A" "%%B%%~xA"
…and if you want to specify the base directory name then you can do so like the following two examples which use %UserProfile% for demonstration purposes, (change as appropriate).
#Echo Off
For /R "%UserProfile%" %%A In ("* * *.csv"
) Do For /F "Tokens=2" %%B In ("%%~nA") Do Ren "%%~A" "%%B%%~xA"
and:
#Echo Off
CD /D "%UserProfile%" 2>Nul||Exit /B
For /R %%A In ("* * *.csv"
) Do For /F "Tokens=2" %%B In ("%%~nA") Do Ren "%%~A" "%%B%%~xA"
Instead of splitting the names using character numbers, this simply takes the second token of the file name string delimited by spaces and adds the original file extension to it in a rename command.
how can i modify filenames in a folder based on delimiters in the filename?
I have a folder with images that get picked up by a different program based on a schedule- the program can only analyze the images if it contains just the main name (sku#) not the additional data that the photographers add after the name
using the command line can i run some sort of script to modify the filenames & delete all characters from after an underscore or hyphen (also need to delete underscore or hyphen)
(i dont know if & how its possible to do this thru the windows command line but i do have the option of running such a 'script' in cygwin- I prefer to use whatever works best...)
I haven't had a need to do this: but with a quick search I found this link on another Stack Exchange site.
A few people uploaded some powershell scripts. The top answer is a GUI tool to do mass name-changes.
There is this CMD example:
dir /B > fileList.txt
for /f "tokens=1,2,3" %i in (fileList.txt) DO ren "%i %j %l" %l
The first line outputs the list of files into a file called fileList.txt. The second line separates each of the names in the list into 3 parts, the #, the "-" and the rest of the name. For each of those it does the rename command.
#ECHO OFF
SETLOCAL
FOR /f "delims=" %%a IN ('dir /b /a-d ^|findstr "_ -"') DO (
FOR /f "delims=_-" %%i IN ("%%a") DO ECHO REN "%%a" "%%i%%~xa" 2>nul
)
FOR /f "delims=" %%a IN ('dir /b /a-d ^|findstr "_ -"') DO ECHO failed ON "%%a"
This should do the job.
First step is to perform a directory listing in /b basic form (without headers - names only) and /a-d without directory names. This is filtered by findstr on (either underscore or dash) and %%a acquires each filtered filename in turn.
The next step is to take those filenames and split them into the parts on either _ or -. The first token (up to, but not including the delimiter) is applied to %%i, so the rename required is from "%%a" (the original filename) to "%%i%%~xa" - the first token+the extension from the original filename.
It's quite possible that the attempt to rename will fail because the new name already exists, so the error message is simply ignored (2>nul)
Finally, look for any un-renamed files and report them (optional, of course)
Note that the REName command is merely ECHOed. This ensures nothing is actually changed while you verify this is what you want to do. Simply remove the ECHO before the REN to activate the rename.
