Mass renaming of files? - windows

I have a folder with 46 different text files, from 001.txt to 046.txt and I need to add another file to, say, spot 30. Is there a ways to rename all the files from 030.txt until 046.txt up by one number, so there is an empty spot for the new 030.txt? (Operating on Windows 7)

You can use PowerShell, which is build-in in Windows 7:
46..30|Rename-Item -Path {'{0:000}.txt'-f$_} -NewName {'{0:000}.txt'-f($_+1)}

#ECHO Off
SETLOCAL
SET "sourcedir=U:\sourcedir\t w o"
SET "insertat="
SET /p "insertat=Insert at which number ? "
IF NOT DEFINED insertat GOTO :EOF
SET /a insertat1=1%insertat%
SET /a howmany=1
SET /p "howmany=Insert How many ? [%howmany%]"
IF "%howmany%"=="0" GOTO :EOF
FOR /f "delims=" %%a IN (
'dir /b /o-n /a-d "%sourcedir%\*.txt" '
) DO (
CALL :isnum %%~na
IF NOT DEFINED notnumber SET /a maxnum=1%%~na&GOTO insert
)
ECHO maxnum NOT found
GOTO :eof
:insert
SET /a newnum=maxnum + howmany
IF EXIST "%sourcedir%\%maxnum:~1%.txt" ECHO(REN "%sourcedir%\%maxnum:~1%.txt" %newnum:~1%.txt
SET /a maxnum -=1
IF %maxnum% GEQ 1%insertat% GOTO insert
GOTO :EOF
:: Determine whether %* is purely numeric
:isnum
SET "notnumber=%~2"
IF DEFINED notnumber GOTO :EOF
SET "notnumber=9%~1"
FOR /l %%z IN (0,1,9) DO CALL SET "notnumber=%%notnumber:%%z=%%"
GOTO :eof
I may as well post this regardless.
It automatically locates the highest filenumber and allows any number of slots to be inserted (default of 1 for Enter)
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.

Here is a simple pure batch solution
#echo off
setlocal enableDelayedExpansion
set increment=1
set "start=030"
for /f %%F in (
'dir /b /a-d /o-n ???.txt^|findstr /rx "[0-9][0-9][0-9]\.txt"'
) do if "%%~nF" geq "%start%" (
set /a new=1%%~nF+increment
ren %%F !new:~1!%%~xF
)

Batch How to avoid a same 2nd FOR loop?

I have created a batch script to backup some subfolders from a path A to a path B (Z:\Folder1\… > U:\Backup\…).
The script lists the subfolders inside path A and increments a number for each of them.
Then, I just have to enter the number(s) of the subfolder(s) I want to backup and xcopy does the rest.
The problem is that sometimes I have thousands of subfolders in path A and only a few to backup (10 or 15).
What I would like is that once I enter the number of these folders, it will go straight to the backup without having to loop all the subfolders inside path A AGAIN (which take time).
Here is my batch :
#echo off
setlocal EnableDelayedExpansion
rem Script for backuping some subfolders from path A to path B
set BackupLocation=U:\Backup
set subfolder_no=1
FOR /F "delims=" %%a IN ('dir /b "Z:\Folder1\*"') DO (
set subfolder=%%a
if defined subfolder (
echo !subfolder_no! !subfolder!
set /a subfolder_no+=1
)
)
set /a subfolder_no=%subfolder_no%-1
set /a index=0
set /a choice=-1
echo.
set /p choice=Enter the number(s) of the subfolder(s) you want to backup:
FOR /F "delims=" %%a IN ('dir /b "Z:\Folder1\*"') DO (
set subfolder=%%a
if defined subfolder (
set /a index+=1
)
FOR %%f IN (%choice%) DO if %%f==!index! (
echo.
echo Backuping subfolder !subfolder!
xcopy "Z:\Folder1\!subfolder!" "%BackupLocation%\!subfolder!\" /e /i /y
)
)
echo.
pause
exit
How can I do this ? Is it possible to get the subfolders' name from their matching number and store them in variables or something ?
Thanks a lot for your help !
Here's an example which only enumerates the directories once.
Please note, whilst it technically answers your question, and performs the task you require of it, this version is designed to work as intended on Windows 10. The specific part you asked about works in other versions too, but the :BackUp labelled section uses a new and undocumented Windows 10 feature of the sort command, to return only unique items from the selection list. Without that, your end user could tehnically provide the same number multiple times, and thus trigger multiple backups of the same directory. As this part of the code is technically outside of the scope of your question, I will leave it up to you to modify the code section yourself, should you be deploying this on older Operating Systems.

How to process a list of file/folder names in a FOR loop which can contain also an exclamation mark?

I write batch script to find contents for file in folder. Contents are in text file and have special characters like exclamation mark.
How do I get FILENAME and FOLDERNAME which contain exclamation mark.

PS: Source folder has many files.
One solution is using a subroutine to avoid usage of delayed environment variable expansion:
#echo off
setlocal EnableExtensions DisableDelayedExpansion

set "SRC="
set /P SRC="Enter source folder link: "
if not defined SRC goto GetSource
set "SRC=%SRC:"=%"
if not defined SRC goto GetSource

set "DST="
set /P DST="Enter destination folder link: "
if not defined DST goto GetDestination
set "DST=%DST:"=%"
if not defined DST goto GetDestination
for /F "eol=| delims=" %%I in ('dir /A-D /B /S "%SRC%" 2^>nul') do (
if exist "%SRC%\Content.txt" for /F "tokens=2,3" %%A in ('%SystemRoot%\System32\findstr.exe /C:"%%~nI" "%SRC%\Content.txt" 2^>nul') do (
set "NEWNAME=%%~A"
set "FOLDERNAME=%%~B"
call :MakeLink "%%I"
)
)
endlocal
exit /B
:MakeLink
echo %~n1
set "NEWNAME=%NEWNAME:_= %"
set "FOLDERNAME=%FOLDERNAME:_= %"
if not exist "%DST%\%FOLDERNAME%" md "%DST%\%FOLDERNAME%"
mklink "%DST%\%FOLDERNAME%\%NEWNAME%%~x1" %1
goto :EOF
Open a command prompt window and run call /? for help explaining how to use the command CALL with enabled command extensions to run a block in same batch file like a subroutine. See also Where does GOTO :EOF return to?
I have not studied your code, but I'd assume that enabling the delayed expansion after setting the variable names would be more appropriate:
#Echo Off
SetLocal DisableDelayedExpansion
Set /P "SRC=Enter source folder link: "
Set /P "DST=Enter destination folder link: "
For /D /R %%A In (*) Do For /F "Tokens=2-3" %%B In (
'FindStr/C:"%%~nxA" "%SRC%\Content.txt" 2^>Nul') Do (Echo %%~nA
Set "NEW=%%B"
Set "FLD=%%C"
SetLocal EnableDelayedExpansion
If Not Exist "%DST%\!FLD:_= !\" MD "%DST%\!FLD:_= !" 2>Nul && (
MkLink "%DST%\!FLD:_= !\!NEW:_= !%%~xA" "%%A")
Endlocal)
Exit /B
I would strongly suggest you perform some proper verification of the user input prior to performing tasks using them, i.e. before the For loop.

Move files into folders based on their names

I have some files in the form:
filename1 1.ext
filename1 2.ext
filename1 3.ext
...
filename2 1.ext
filename2 100.ext
...
filename20 1.ext
filename20 15.ext
(etc.)
...where filename can contain spaces.
And I want to move them to folder filename1, filename2, etc., respectively.
I know I can do a for loop for %%i in (*.ext) do and remove the extension with set folder=%%~ni. So what I am missing is how to remove everything after the space just before the number, and get only filename1, for example.
I also know I can split variable folder, but in this case I do not know by at which character I need to split, although I know it will be a space followed by a number.
So basically, I want something like this:
#echo off
set folder=
for %%i in (*.ext) do set folder=%%~ni & set folder=getfoldernamefromvariablefoldersomehow & mv %%i %folder%
#ECHO OFF
SETLOCAL
SET "sourcedir=U:\sourcedir"
FOR /f "delims=" %%a IN (
'dir /b /a-d "%sourcedir%\*.ext" '
) DO (
CALL :sub1 "%%a" %%a
)
GOTO :EOF
:sub1
SET "filename=%~1"
:subloop
SHIFT
SET "numname=%~1"
IF NOT "%~2"=="" GOTO subloop
CALL SET "dirname=%%filename: %numname%=%%
ECHO( MD "%sourcedir%\%dirname%" 2>nul
ECHO( MOVE "%sourcedir%\%filename%" "%sourcedir%\%dirname%\%numname%"
GOTO :eof
You would need to change the setting of sourcedir to suit your circumstances.
The required MD commands are merely ECHOed for testing purposes. After you've verified that the commands are correct, change ECHO(MD to MD to actually create the directories.
The required MOVE commands are merely ECHOed for testing purposes. After you've verified that the commands are correct, change ECHO(MOVE to MOVE to actually move the files. Append >nul to suppress report messages (eg. 1 file moved)
Perform a directory list of the required files in basic form without directorynames. Send the full fulename in quotes and without to the subroutine sub1.
In the subroutine, save the source filename in filename then shift each parameter supplied until there is no second parameter; the value in numname must then be the last or required filename.
Remove numname with a leading space from filename to get the required subdirectoryname, make that subdirectory and move the file.
[edit in the light of comment]
#ECHO OFF
SETLOCAL
SET "sourcedir=U:\sourcedir"
FOR /f "delims=" %%a IN (
'dir /b /a-d "%sourcedir%\*.ext" '
) DO (
CALL :sub1 "%%a" %%a
)
GOTO :EOF
:sub1
SET "filename=%~1"
SET "destdirname=%~2"
:subloop
SHIFT

CALL SET "dirname=%%filename: %numname%=%%
ECHO( MD "%sourcedir%\%destdirname%" 2>nul
ECHO( MOVE "%sourcedir%\%filename%" "%sourcedir%\%destdirname%\%numname%"
GOTO :eof
It's difficult to scry your intentions when you give no example.
destdirname is set to the second parameter on entering sub1 which will be the first group of characters before the first space.
the md does not need to be gated since the 2>nul will suppress the directory exists error message.
Here is a script that does what you want. It splits off the last SPACE followed by numerals from the file name and uses the remaining string as the name of the destination directory of the movement.
This approach handles all valid characters for file names properly, even ^, &, %, !, ( and ). It can even handle file names that contain SPACE plus numerals plus .ext again correctly.
So here is the code:
#echo off
setlocal EnableExtensions DisableDelayedExpansion
rem // Define constants here:
set "_SOURCE=."
set "_TARGET=."
for /F "eol=| delims=" %%F in ('
dir /B "%_SOURCE%\*.ext" ^| findstr /R /I /C:" [0123456789][0123456789]*\.ext$"
') do (
set "FILE=%%F"
call :SPLIT LAST REST "%%F"
setlocal EnableDelayedExpansion
2> nul mkdir "!_TARGET!\!REST!"
ECHO move /Y "!_SOURCE!\!FILE!" "!_TARGET!\!REST!"
endlocal
)
endlocal
exit /B
:SPLIT rtn_last rtn_rest val_string
setlocal DisableDelayedExpansion
set "RES=" & set "STR=%~3"
:LOOP
for /F "tokens=1,* delims= " %%I in ("%STR%") do (
if "%%J"=="" (
set "RES=%%I"
) else (
set "STR=%%J"
goto :LOOP
)
)
set "STR=%~3|"
call set "STR=%%STR: %RES%|=%%"
(
endlocal
set "%~1=%RES%"
set "%~2=%STR:^^=^%"
)
exit /B
After having tested the script, remove the upper-case ECHO command to actually move any files. Unless you remove the /Y option from the move command, files become overwritten without prompt. To suppress summary messages (like 1 file(s) moved.), add > nul to the move command line. Note that any prompt was also hidden then in case you removed the /Y option.
Thank to all of you for your comments. Finally, i was able to get a solution:

batch file calling to function fail

been trying to figure how to make the random string generation as a function, then call to function to return new random for each for loop.
but unable to make it work...
blank of idea, batch programming seems lot more complicated than web..
#echo off

set orig=%1
set %~2=%random%

echo !fname!
ren "!fname!" img_%date:~10,4%-%date:~4,2%-%date:~7,2%_%HR%%time:~3,2%-!random!.png
endlocal
)
goto :eof
Original question answered (before edit). Explanation:
Use for /F against dir /b as unlike for /F, for starts parsing files immediately so it could get a renamed file again and again...
File renaming treated in a subroutine with test on file existence before ren.
Note endlocal&set "%1=%_RndAlphaNum%"&goto :eof tricky part how-to return a value to a variable (parameter) passed by reference.
ren command echoed merely for debugging purposes.

Rename files with different extensions via Windows batch

I've spent two days on this and have looked at most every forum file I can find. Here's the scenario:
I have tens of thousands of image files: img_123.jpg, img_124.cr2, img_125.mov, etc. and I need them named: 64,001.jpg 64,002.cr2 64,003.mov and so on. Basically renaming the file while keeping the original extension in tact, while putting a comma in the thousands position.
Thanks to reading through the helpful Q&A's on Stack Overflow, I was able to write something that either A) renames the files serially but with no comma (64001.jpg 64002.cr2 64003.mov, etc.); or B) renames only the very first file for a unique type (img_123.jpg becomes 64,001.jpg just fine, while img_124.jpg img_125.jpg, etc. each fail with an error saying the filename is not unique.
Here's my code:
#ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET "sourcedir=c:\sourcedir"
SET /a num=64000
FOR /f "delims=" %%a IN (
'dir /b /a-d "%sourcedir%\*" '
) DO (
IF !num! lss 1000000 (
SET "newname=!num:~0,-3!,!num:~-3!"
) ELSE (
SET "newname=!num:~0,-6!,!num:~-6,3!,!num:~-3!"
)
ECHO REN "%sourcedir%\%%a" "!newname!%%~xa"
SET /a num+=1
)
GOTO :EOF
All you'd need to do is set up sourcedir to suit your system.
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.
Here's what worked, thanks to Magoo for coming up with 95% of this.
#ECHO OFF
