Hi

i am trying to creat at batch file that will add the date/time into a file name, i need to keep the origional file name intact but have the date/time reference to avoid duplication

any ideas?

This is depends on so many things, one of which is your local date format. I'm really not understanding the question. As you pointed out, you can't have duplicate file names in a folder, so adding the date/time really does nothing. This then becomes more a function of what program(s) are adding files to the folder. It is these programs that should be adding the date/time stamps as part of the file name.

This little snippet will tack on date/time to existing files in a folder. Test this in a trash directory as the files names look rather funky.

Code: [Select]

@echo off
setlocal enabledelayedexpansion
pushd %cd%
cd /d c:\temp

set search=/
set replace=-

set search1=:
set replace1=.

for /f %%i in ('dir /a-d /b') do (
  set newName=%%~ni-%date%-%time%
  set newName=!newName:%search%=%replace%!
  set newName=!newName:%search1%=%replace1%!
  ren "%%i" "!newName!%%~xi"
) 

popd

You need to change the cd (4th lne) directory to something appropriate. 

Good luck.

I need to keep the original file name intact but have the date/time reference to avoid duplication

"set newName=%%~ni-%date%-%time%"
%date% as part of file name will not copy or ren ( rename ). Certain characters are not allowed as part of file name.
A file name cannot contain any of the following characters:

/ \ : * ? “ < >

C:\>type  sidew.bat

Code: [Select]

@echo off
setlocal enabledelayedexpansion

for /f "tokens=1-4 delims=/- " %%a in ('date /t') do (
set mm=%%b
set dd=%%c
set yy=%%d
)

for /f "delims=" %%i in ('dir /b  a*.txt') do (
echo  %%~ni
set newName=%%~ni


set newName=!newName!!mm!!dd!!yy!.txt
echo newName = !newName!

copy "%%i" "!newName!"
)
Output:

The following is Sidewinder's code ( post 1) with slight modification and the output is listed.  What does pop and push do?  How does set search=/  and set replace=- work?


C:\batch>type loose.bat

Code: [Select]

@echo off
setlocal enabledelayedexpansion
pushd %cd%

set search=/
set replace=-

set search1=:
set replace1=.

for /f %%i in ('dir /a-d /b a*.txt') do (
  set newName=%%~ni-%date%-%time%
  set newName=!newName:%search%=%replace%!
  set newName=!newName:%search1%=%replace1%!
  copy "%%i" "!newName!%%~xi"
)

popd
Output:

C:\batch>loose.bat
        1 file(s) copied.
        1 file(s) copied.
