Batch File - Check file exists

I don't know if this can be done with batch scripting, but I need to check in a folder to see if all the text files in that folder already exists in another or not.  Or if I can read the network folder.

I have a folder called "JOBS" that has 2 sub folders "Archive" and "Error".  The bat script will copy all files with extension "txt" into a network folder "\\bb\nlc\tr\JOBS".  Once it's done copying, it'll check and see if the same file from "JOBS" exists in the network folder "JOBS".  If it does not exists or can't read the network folder, move all the files into a folder called "Error".  If it exists, then move it to a folder called "Archive".

Is this even doable with batch jobs?  I know the moving and copying can be done.  Just not sure about the checking if a file exists or can read/see the network folder.

You would need to do it on a one by one basis, but you can do it:

for %%f in ("MyDir\*.txt") do (

             if exist %%f (
                 rem file exists -> do something
             ) else (
                 rem file doesn't exist -> do something else.
             )

    )



type "help if" in a command prompt for more info.

Something along these lines sounds like what you are after.... can always add in some logging or error checking etc. as needed.

@Echo off

Set SourceDir=C:\jobs
Set DestDir=\\bb\nlc\tr\JOBS

CD /d "%Sourcedir%"

xcopy /y /d *.txt "%DestDir%"

For /f "tokens=*" %%a in ('dir /b /a-d %Sourcedir%\*.txt') do (
  if exist "%DestDir%\%%~a" (
    MOVE "%Sourcedir%\%%~a" "%Sourcedir%\Archive"
  ) ELSE (
    MOVE "%Sourcedir%\%%~a" "%Sourcedir%\Error"
  )
)

Here is a slightly different approach. During the COPY command we check for success or fail and move the file being copied to the appropriate folder.  Seems a little cleaner...

@echo off
setlocal

set BaseDir=c:\jobs
set GoodDir=archive
set BadDir=error
set DestDir=\\bb\nlc\tr\jobs

for %%A in ("%BaseDir%\*.txt") do (
  copy "%%~A" "%DestDir%" && (
    move "%%~A" "%BaseDir%\%GoodDir%"
  ) || (
    move "%%~A" "%BaseDir%\%BadDir%"
  )
)
