VBScript or Batch file to compress log files and move to another drive

I need a VBScript or Batch file to zip all the .log files in the various subfolders of %windows%\System32\LogFiles that are, say 14 days or older and move them to a different drive:\folder.

I found this thing  http://winadmin.forret.com/scripts/warmzip/
It's suppose to allow you to script compressing and moving files.  It looks very promising, but I got an error when I ran one of the sample batch files.

Thanks in advance.

I found this and modified the folder path to mine, but this script only does one folder.  I need to look in about 28 folders in the LogFiles folder and process each of them.  I haven't tested the code below either...
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

'' This script will find logs that are more than a day old and ''

'' compress them.                                              ''

'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

Option Explicit

         

Dim objFSO, objFolder, objFiles, objShell

Dim file, fileExt, fileName, strCommand, strRun, strFile

Dim Folder, Extension, DaysOld, log

Dim strYear, strMonth, strDay, strHour, strMinute, strSecond 



 

Const ForReading = 1, ForWriting = 2, ForAppending = 8

 

         

'''' SET THESE VARIABLES! ''''

Folder = "C:\WINDOWS\system32\LogFiles"      'Folder to look in

Extension = "log"        'Extension of files you want to zip

DaysOld = 7        'Zip files older than this many days

''''''''''''''''''''''''''''''

         

'Create object for playing with files

Set objFSO = CreateObject("Scripting.FileSystemObject")

         

'Create shell object for running commands

Set objShell = wscript.createObject("wscript.shell")

         

'Set folder to look in

Set objFolder = objFSO.GetFolder(Folder)

         

'Get files in folder

Set objFiles = objFolder.Files

 

'Set text file to write to

FileName = "C:\WINDOWS\system32\LogFiles\Log_Processing.txt"

 

Set log = objFSO.OpenTextFile(FileName, ForAppending)

 

         

'Loop through the files

        For Each file in objFiles

          fileName = Split(file.Name, ".")

          fileExt = fileName(UBound(fileName))

          'See if it is the type of file we are looking for

          If fileExt = Extension Then

            'See if the file is older than the days chosen above

            If DateDiff("d", file.DateLastModified, Now()) >= DaysOld Then

              strFile = file.Path

              strCommand = "7z -mx=7 -y a C:\WINDOWS\system32\LogFiles\web_log_compressed\" & _

                ShortDateTime(Now) & ".zip " & Chr(34) & strFile & Chr(34)

              strRun = objShell.Run(strCommand, 0, True)

              log.WriteLine strCommand

              file.Delete

              log.WriteLine "Deleted " & strFile

            End If

            

          End If

        Next

         

        'Cleanup

        Set objFiles = Nothing

        Set objFolder = Nothing

        Set objFSO = Nothing

        Set objShell = Nothing

        wscript.Quit

        

Function ShortDateTime(dtmTime)

    strYear = Year(dtmTime)

    strMonth = Right("0" & Month(dtmTime), 2)

    strDay = Right("0" & Day(dtmTime), 2)

    strHour = Right("0" & Hour(dtmTime), 2)

    strMinute = Right("0" & Minute(dtmTime), 2)

    strSecond = Right("0" & Second(dtmTime), 2)

    

    ShortDateTime = strYear & strMonth & strDay & "-" & strHour & strMinute & strSecond

End Function

WHy not just use WinZip with the commandline version, and do it all with one neat little command?  Something like this should do the job:

wzzip -m -Td14 "d:\destfolder\destfile.zip" "%windows%\System32\LogFiles"

I guess that woud be the simplest way to do it.  There is really no good reason to do each folder separately.  I've never used the commandline version of WinZip.  If it will grab just the *.log files that are >14 days old from all the sub folders then that will work a charm.
Can you have it delete the source files after zipping them?  It doesn't help if they are left lying around.  I need to do this to free up hard drive space on a db server.

Yes, wzzip can delete the source files, I added the -m option to the command line (standing for move) that does exactly that.  And yes, it could handle just *.log files like:

wzzip -m -Td14 "d:\destfolder\destfile.zip" "%windows%\System32\LogFiles\*.log"

Thank you so much!  Now we can free up enough space on the system drive of our SQL Server to do an upgrade.
You just saved my company $15,000.00 by not having to buy a new server.  ;-)
