Random renaming all .exe files in a folder using batch - file

What I want to accomplish is to rename all the .exe that I have in a folder.
Sample of random name should be "589uday5xpsa9iz.exe"
I would appreciate any help I can get on this, I have been trying to figure it out for a couple of days now.

Try this :
#echo off
setlocal enabledelayedexpansion
:://The string length of the output
set $Lcode=16
set $#=#
:://The char Map
set $l="#0=0" "#1=a" "#2=B" "#3=c" "#4=d" "#5=E" "#6=f" "#7=g" "#8=H" "#9=I" "#10=j" "#11=K" "#11=1" "#13=2" "#14=3" "#15=4" "#16=5"
:://Evaluating the char MAP
for %%a in (%$l%) do set %%~a
:://Looping in the directory for .exe files
for /f "delims=" %%x in ('dir /b/a-d "*.exe"') do (
for /l %%a in (0,1,%$Lcode%) do (
call:rand
)
ECHO ren "%%x" !$Fstring!.exe
set $Fstring=
)
pause
exit/b
:://Getting the random Char
:rand
set /a $n=!random!%%17
set $Fstring=!$Fstring!!#%$n%!
I made a char MAP of just 15 char but you can increase it with all the char (up and downcase + number). If you do it. You have to increase the value in !random!%%17
with the value of the total CHAR map(+1).
You can increase the length of the random string by changing the value in the variable : $Lcode (16) in this example.
The output :
ren CnpjSdee.exe 2aHg5I22EBBE2ff5.exe
ren DbatchCnpj.exe EIIg2E54aHHIEgfHE.exe
ren NTStreamColor.exe jg03f3dIfBfIfHj2.exe
ren savedialog.exe EgfdajIcdc2cf03E.exe
Press any key to continue. . .
If it's OK Remove the ECHO to realy rename the files.

this is a simple batch that will work from within the folder that contains the files to be renamed you could make a shortcut to use it from the desk top. use copy and paste for long names. C:\Documents and Settings\Owner\Desktop\New Folder\Rename.bat (file = Rename.bat) don't use the whole path.
#echo off
title Rename Bat
echo This bat must be in the folder that
echo contains the files to be renamed.
:begin
echo Enter File Name
set /p old=
echo Enter New Name
set /p new=
ren "%old%" "%new%"
echo File Renamed
ping -n 3 127.0.0.1 >NUL
goto begin
hope this works for you.

a much simpler approach ... try a for loop that cycles through all files in that folder and renames them one at a time giving each a unique number ...
#echo off
for /L %%n in (1 1 %random%) do (
for %%a in (*.exe) do (
rename "%%a" "%%a_%%n.exe"
)
)
so %%a represents all the files in that folder and %%n represents the unique number that is going to be assigned to each file in the for body separated with _ symbol
to use this batch file you have to place it in the folder containing your .exe files
this would rename files to original name_1 then original name _2 and so on if you want it to be completely random use only %random% in bracket of the first for loop and do away with the iteration "1" (see below) also at the renaming part do away with %%a to omit the original name of file so that you remain with only random numbers also see below e.g
#echo off
for /L %%n in (%random%) do (
for %%a in (*.exe) do (
rename "%%a" "%%n.exe"
)
)
hope this helps .....

How to batch transfer rename?

There are two folders holding equal amounts of files between them.
I'd like to apply the names from one set ; to the other set of files in no particular order. Inherit the name, but retain the extension .
Input files are .bmp Output files are .ini ( has a gear symbol ).
Example :
folder 1- Flowers.bmp ; folder 2- blank.ini
. To this:
folder 1- Flowers.bmp ; folder 2- Flowers.ini
There would be more files , but equal .
The .ini files are all copies . So they may have a generic name and numbered if that matters to know . Those would all receive one name each from the other .bmp files in the other folder.
Normally I have both folders situated on the Desktop .
I make sure both folders have equal number of files between them . That would be a constant .
I'm trying to stream line some menial repetitive daily tasks .
I did search and what I have found does not really help.
#ECHO OFF
SET "vers=%~1"
IF "%vers%" == "" SET /P "vers=Enter Vers: "
FOR %%F IN (file_XX_*.*) DO CALL :process "%%F"
GOTO :EOF
:process
SET "name=%~nx1"
SETLOCAL ENABLEDELAYEDEXPANSION
SET "name=!name:_XX_=_%vers%_!"
RENAME %1 "%name%"
ENDLOCAL
Hoping to find a solution to this finally .
Ok, here is a slightly long version, but it makes sure it gets the content of each folder.
Note You must ensure that the path to both folders are correctly specified in the third and fourth line:
#echo off
setlocal enabledelayedexpansion
set "source=%userprofile%\Desktop\folder 1"
set "destination=%userprofile%\Desktop\folder 2"
set /a num=0
for %%a in ("%source%\*") do (
set /a num+=1
set "fr!num!m=%%~na"
)
set /a oldn=!num!
set /a num=0
for %%b in ("%destination%\*") do (
set /a num+=1
set "to!num!r!=%%~nxb"
set "ext=%%~xb"
)
pushd "%destination%"
for /l %%i in (1,1,!oldn!) do ren "!to%%ir!" "!fr%%im!%ext%"
popd
pause
You can remove pause at the bottom of the script, once you are happy with the output.
This is not the most effective way, but considering your limited batch experience, I guess an understandable approach is better than an optimized one (using array-like variables).
#echo off
setlocal enabledelayedexpansion
(for %%A in ("folder 1\*.bmp") do echo %%~nA)> "%temp%\names.txt"
<"%temp%\names.txt" (
for %%A in ("folder 2\*.ini") do (
set /p "name="
ECHO ren "%%A" "!name!.ini"
))
The first for loop creates a list of the desired names (from Folder 1). The modifier %%~nA returns the name only.
The second for processes each file in Folder 2 and takes a name from the previously generated file for each file. This depends on the fact that the number of files in both folders are the same, else you may get undesired results.
I disabled the actual ren command by just echoing it. Check the output and only when you are satisfied, remove the ECHO.

Batch Finding and displaying duplicate strings in file names

I have a question. Is it possibile in batch language to search in folder a part of name that is same like another file and display it.For example i got folder with files :
ggggggsss.mp3
ddddddeee.mp3
ddddddff.mp3
ssssssddd.mp3
aaaaasssss.mp3
11111ssdas.mp3
11111dddd.mp3
...
I need to display in cmd only names of files
ddddddeee
ddddddff
and
11111ssdas
11111dddddd
Because the first six letter are the same. Could someone help me with this problem?
Save this script to test.bat and run from open Cmd Prompt. Replace dir value with path to your folder with .mp3 files:
#echo off
setlocal enabledelayedexpansion
set "dir=%userprofile%\music"
set "pattern1=dddddd" & set "pattern2=11111"
pushd "%dir%"
FOR %%G IN (*.mp3) DO ( set song=%%G
if "!song:~0,6!"=="%pattern1%" echo %%G)
echo/
FOR %%G IN (*.mp3) DO ( set song=%%G
if "!song:~0,5!"=="%pattern2%" echo %%G)
popd
exit /b

Batch script to return files NOT duplicated with a different extension

I don't have much experience with batch scripting but this seems like a suitable task for it:
I have a very large directory with recordings of a specific extension, say '.wav'. In the same folder, I'm supposed to have, for each of these recordings, an xml file, named the exact same as the recording filename, except with the extension .xml instead of .wav.
Now, I notice that the '.xml' files total count is slightly less then the '.wav' total; i.e some of the xml files are missing.
How can I extract a list of all recordings with missing xml files?
#echo off
for %%F in (*.wav) do if not exist "%%~dpnF.xml" echo %%F
You don't really need a batch file. You could enter the following directly on the command line:
for %F in (*.wav) do #if not exist "%~dpnF.xml" echo %F
Actually, you don't need the ~dp modifiers as I have written the code. But if you include path information like in (somepath\*.wav), then they become important.
This a little approch can did the trick
You should just change Set folder=c:\temp to your folder that contains your files :
#echo off
set folder=c:\temp
set ext1=wav
set ext2=xml
Set Log=c:\MissingFiles.txt
set /a count=0
cd /d "%folder%"
setlocal enabledelayedexpansion
(
for %%a in (*.%ext1%) do (
for %%b in (*.%ext2%) do (
If /I not "%%~na"=="%%~nb" ( SET /A COUNT+=1 && echo "%%~dpnxb" )
)
)
echo.
ECHO The total number of missing files is !COUNT!
Endlocal
) > %Log%
Start "" %Log%

Using batch files to remove a single number from a folder name

At work we use a bespoke program to search through a directory tree and find an individual image file. These files are stored in folders that have a 7-digit name, starting with '18' - so for instance '1873456', '1873457', '1873458' etc. The problem I have is at some point last year the procedure that creates these folders and populates the images in them reached '1899999' - and then rolled over to '18100000' and carried on like that for over 4,000 folders before it was caught and corrected.
The bespoke program we use can only handle seven-digit folder names. What I would like to do is create a batch file that renames all the eight-digit folders by removing the extra '1' in the name, so '18100000' becomes '1800000' and so forth until '18104013' becomes '1804013'.
Can anyone help?
Run this in the base folder, it will not change any folders.
A file called renfile.bat.txt will be created that contains the rename command for the folders that match the filespec. Examine it in notepad to see if it is ok and then rename it to renfile.bat and run it.
It's not tested.
#echo off
setlocal enabledelayedexpansion
for /d /r %%a in (18??????) do (
set "name=%%~nxa"
>>renfile.bat.txt echo ren "%%a" "!name:~0,2!!name:~3!"
)
Something like
for /l %%x in (100000,1,104013) do (
set oldsuffix=%%x
set newsuffix=%oldsuffix:~-5%
ren 18%%x 18%newsuffix%
)
setlocal enableextensions enabledelayedexpansion
for /d /r "c:\somewhere" %%f in (181?????) do (
set "name=0" & set /a "name+=%%~nf" 2>nul
if !name! gtr 1899999 ren "%%~ff" "18!name:~-5!"
)

How to use batch job to add the file "create date" into all the files in a directory?

I have a folder that gets a new file added everyday to the folder with the same file name but incremental extension such as .001, .002, .003, etc. However, if there's no file within the folder it starts at .001 again.
The problem is they are all named the same and if I move them to another folder to archive them it would just overwrite the same file over and over again. I could create a folder each day with the date with only one file in it, but that seems a bit redundant.
Is there a way to look at the create date of each file and rename it to the create date?
I've gotten this far, but it looks like for this situation I have to use a static file name, how to loop through the entire directory?
SET filename = C:\test.001
FOR %%f IN (%filename%) DO SET filedatetime=%%~tf
rename c:\test.001 C:\test_%filedatetime%.txt
move C:\*.txt C:\archive\
this provides the correct sort order:
#echo off &setlocal disableDelayedExpansion
set "startfolder=%userprofile%\test"
cd /d "%startfolder%"
for %%a in (*) do (
for /f "delims=." %%b in ('wmic datafile where "name='%startfolder:\=\\%\\%%~a'" get lastmodified^|find "."') do (
echo(ren "%startfolder%\%%~a" "%%~b.txt"
)
)
Remove echo to get it working.
#ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET "targetdir=c:\sourcedir"
SET "destdir=c:\destdir"
PUSHD "%targetdir%"
FOR %%a IN (*.*) DO (
SET "timestamp=%%~ta"
SET "timestamp=!timestamp:/=_!
SET "timestamp=!timestamp::=_!
SET "timestamp=!timestamp:.=_!
SET "timestamp=!timestamp:,=_!
SET "timestamp=!timestamp: =_!
ECHO MOVE "%%a" "%destdir%\%%~na.!timestamp!"
)
GOTO :EOF
This should work with any file in the nominated target directory where the name does not include ! or ^.
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)
The gymnastics around timestamp are intende to replace /: with _ since these are illegal filename characters. Space., are similarly replaced - they're legal but often painful.
If you want the destination filename to be name.003.timestamp, remove the ~na from the destination name.
Try like this :
SET $path=The_path_who_contain_the_FILES
FOR /F "DELIMS=" %%f IN ('dir "%$path%" /a-d/b') DO (
SET filedatetime=%%~tf
move "%%~dpnxf" "C:\archive\test_%filedatetime%.txt")
