This question already has an answer here:
At which point does `for` or `for /R` enumerate the directory (tree)?

I tried to change names *.txt files, but i have a problem I can't solve.
I would like to give prefixes to *.txt files entered by user input, but the code I have adds, without knowing why, a doubled prefix for one file.
#echo off
SET /p Input=Enter prefix wanted:
Echo You entered: "%Input%"
Pause
for %%a in (*.txt) do ren "%%a" "%Input%%%a"
before using the code:
1.txt
2.txt
3.txt
after using the code with prefix added by user:
test1.txt
test2.txt
testest3.txt
Do you know the solution to my problem?
Use
for /f "delims=" %%a in ('dir /b *.txt') do ...
The problem is that when the file is renamed, the for looks for the next file in the directory - which could be the new name of the file.
The code I've provided builds a file list in memory, then processes the list, so it doesn't see the new name of the file.

I would like to append my folder name to all the available .txt files inside a subfolder. Below is the file/directory structure. I need to achieve this in Windows BATCH script.
C:\Source\Source1\1\a.txt C:\Source\Source1\1\b.txt
C:\Source\Source1\2\a.txt C:\Source\Source1\2\b.txt
C:\Source\Source2\3\a.txt C:\Source\Source2\3\b.txt
The above files should be renamed like below:
C:\Source\Source1\1\1_a.txt C:\Source\Source1\1\1_b.txt
C:\Source\Source1\2\2_a.txt C:\Source\Source1\2\2_b.txt
C:\Source\Source2\3\3_a.txt C:\Source\Source2\3\3_b.txt
Similary, I have Source1...Source30 and under each source directory, I will have multiple folders with different numbers. I need to rename all the files under these directories and append the number(directory name) to the file name.
So far below is what I wrote:
for %%* in (.) do set CurrDirName=%%~nx*
echo %CurrDirName%
for /r %%x in (*.txt) do ren "%%x" "%CurrDirName%_%%x"
With this, I am able to achieve it in a single directory. I couldn't make it recursive. Could you guys please help me with this.
#echo OFF
SETLOCAL EnableExtensions
for /F "delims=" %%G in ('dir /B /S "C:\Source\*.txt"') do (
for %%g in ("%%~dpG.") do ECHO rename "%%~fG" "%%~nxg_%%~nxG"
)
pause
where the FOR loops are:
outer %%G loop creates a static list of .txt files (recursively), and
inner %%g loop gets the parent folder of every particular file.
The rename command is merely displayed using ECHO for debugging purposes. To make it operational, remove word ECHO (no sooner than debugged).
Moreover, I'd consider checking whether a particular file is already renamed…
I am in the need of a batch script that checks a drive (D:) for the 'last modified' attribute of *.czi files (Carl Zeiss image files) and append the data to a file on another drive. I have tried solutions with the following line:
FOR /F "delims=" %%I IN ('DIR %source%*.czi /A:-D /O:-D /T:W /B') DO COPY "%%I" > %target%
that does give me the last file, but it copies the entire file which is not that smart since they can be big. As a biologist I will spare you for my desperate attempts that did not work (spent 4-5 hours). I figure this can be done dead easily, that is if you know how... Any good suggestions? Any reply will be appreciated! Thanks in advance.
Let's assume just the last modified file time from newest file is wanted from all *.czi files in directory C:\Temp containing for example:
30.01.2017 08:13 First Listed.czi
28.01.2017 21:26 Oldest Image.czi
03.02.2017 17:13 Newest Image.czi
The batch code for this task could be:
#echo off
set "Source=C:\Temp\"
set "Target=%Source%List.txt"
for /F "delims=" %%I in ('dir "%Source%*.czi" /A:-D /B /O:-D /T:W 2^>nul') do (
echo File "%%I" last modified on %%~tI>>"%Target%"
goto AfterLoop
)
:AfterLoop
The command DIR searches in for *.czi files in directory C:\Temp and outputs the list sorted by last modification time in reverse order from newest to oldest.
In case of no *.czi file could be found, command DIR would output an error message to handle STDERR. This output message is redirected with 2>nul to device NUL to suppress it whereby the redirection operator > must be escaped here with ^ to be interpreted as redirection operator on execution of DIR command line and not already on parsing FOR command line.
%%I references the name of the file as output by DIR and %%~tI references the last modification date of the file. The help of command FOR output by running in a command prompt window for /? explains those modifiers.
The loop is exited after first output of the text redirected to the target file on which the line is appended if it is already existing because of using >> instead of just >.
For the example files list the following line is appended to C:\Temp\List.txt:
File "Newest Image.czi" last modified on 03.02.2017 17:13
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.
dir /?
echo /?
for /?
goto /?
set /?

Your question is unclear, so let me try to rephrase it:
I think you want to find the Most Recently Modified file with a .CZI extension, and copy only that newest file to some target destination.
To list all .CZI files in all subdirectories, sorted by newest-file first:
(for /f %a in ('dir *.CZI /s /b') do #echo %~ta %~fa) | sort
If the first line of this output is the file that you want, then all you need to do is copy that one file to your target.

I have a lof of files with similar beginning names, but ending different. I have to create a folder for every "series" of files, which means all files whose names begin with the same 7 characers.
See image for visualization:
The code I have right now is
for /F "Tokens=*" %%i in ('Dir /B *.jpg') do md "%%~ni"|copy "%%i" "%%~ni"
Which just creates a folder for every file and puts it inside.
Unfortunately I don't have enough knowledge of this language and just googling it only made me learn how to create a substring SET _result=%_test:~0,7% but not how to create folders with that.
I'm sure it's just a short sequence, could someone help me with that?
This may not be the most efficient way of doing this, but it should help you. The below batch script takes an input folder and output folder as inputs from user. It then iterates through all the files in the input folder and copies them to output folder under a sub-folder with first 7 characters of the filename.
#echo OFF
setlocal ENABLEDELAYEDEXPANSION
REM Get input directory from user
set /p INPUT_DIR=Please enter full path to directory with files:
REM Get ouput directory from user
set /p OUTPUT_DIR=Please enter full path to output directory:
REM Iterate through files and create necessary folders/copy files
for /f %%f in ('dir /b %INPUT_DIR%') do (
set fullname=%%f
set trimmedname=!fullname:~0,7!
set fullpath=%OUTPUT_DIR%\!trimmedname!
if not exist !fullpath! md !fullpath!
copy %INPUT_DIR%\%%f !fullpath!
)
Here's a sample output that shows the processing done by the script:
Can anyone assist me in writing a batch script that searches for file names and outputs the location of the files to a text file. Example I have a file called list.txt located in a folder, C:\LocateFiles\list.txt. Located in the list.txt file are about 25 file names that I wish to determine if they are anywhere on the C:\ drive. If it locates any of the file names identified in the file list.txt it will output the path of all files found to a single file in C:\LocatedFiles\results.txt.
A million thanks,
Johnny Mac
#ECHO OFF
FOR /F %%F IN (C:\LocateFiles\List.txt) DO DIR /s/p/b %%F.* >> C:\LocateFiles\finds.txt
Save that as LocateFiles.cmd and place it in whichever directory you wish to search, note that C:\ is very large and will take quite a while! as in, forever, seriously, i really wouldnt, your call...
the file finds.txt will have the entire path for any file that matches up to the file names listed in List.txt
Also note, this finds files of any extension, but the filename itself must match exactly to whats in List.txt
The solution below search the files in the current directory just once, so it run faster.
#echo off
dir /S /B /A-D | findstr /I /G:C:\LocateFiles\list.txt > C:\LocatedFiles\results.txt
EDIT: New method added
The method below may run even faster. It is necessary to complete a timing test.
#echo off
setlocal EnableDelayedExpansion
rem Read file names from file list and assemble a long string with this format:
rem "filename1.ext*" "filename2.ext*" ...
set "fileList="
for /F "delims=" %%a in (C:\LocateFiles\list.txt) do set fileList=!fileList! "%%a*"
rem Search the files from current directory downwards
(for /R %%a in (%fileList%) do echo %%a) > C:\LocatedFiles\results.txt
I'm a beginner with .bat files, and I'm attempting to rename multiple drawing (.dwg) files using a list generated in notepad. The notepad list contains a list of drawing numbers that look like this:
01013-13000p001
06301-12550p001
etc..
There is hundreds of them, and I want to take those numbers from the text and put it into a blank series of dwg files that are generic named for now (drawing.dwg, drawing(2).dwg, drawing(3).dwg etc..) I've only come up with a way to read a text file, but cant figure out how to take from the text file and rename multiple drawing files with it. Below is as far as I have gotten, after failed attempts of trying to take whats read from a text file and put it into the .dwg files. I plan on working this out in all the same directory, and any suggestions will be greatly appreciated. Thanks.
#echo off
for /f "tokens=* delims=" %%x in (dwgNumbers.txt.txt) do echo %%x
pause
would
for /f "delims=" %%x in (dwgNumbers.txt.txt) do echo copy /b "blank generic drawing.dwg" "%%x.dwg"
(as a batch line) do what you want? - note that the ECHO keyword is there to show what would be done. The echo keyword needs to be removed to actually execute the copy.
This will take the numbers from .txt, renaming the existing .dwg files with the data readed. If there are more files that numbers in .txt, it will rename until number exhaustion, no more.
for loop is using a dir command to get the list of files to avoid the case of files that after being renamed falls under the filter of the for and gets reprocessed.
This code has a echo command included in rename line to prevent data loss in case of malfunction. When the output to console is what is needed, remove the echo command from the rename line.
#echo off
rem Prepare environment
setlocal enableextensions enabledelayedexpansion
rem Read input file for numbers
< dwgNumbers.txt (
rem Process dwg files in directory
for /f "tokens=*" %%f in ('dir /b *.dwg') do (
rem Get number from input file
set "number="
set /p "number="
rem If there is a number, rename the file
if defined number echo ren "%%~f" "!number!.dwg"
)
)
rem Clean
