Recursive folder synchronization using VBScript (Mirror Folders) - vbscript

Question

I've never really written in vbs (once wrote a script that would welcome me on boot) but I'm after a script to essentially perform :
robocopy "folder1" "folder2" /MIR
At the moment what I've got is a copied script from here VBS Mirror, Using the top script :
This code synchronizes the contents (files and subfolders) of two
folders. Each folder is traversed recursively and any missing
subfolders and files are copied both ways. If corresponding folders
contain files with matching file names but with different time stamps,
the file with the newest time stamp will overwrite the older.
SyncFolders.vbs
Option Explicit
ForceScriptEngine("cscript")
Dim wshArgs
Set wshArgs = Wscript.Arguments
If WshArgs.Count = 2 Then
Call SyncFolders(WshArgs.Item(0), WshArgs.Item(1))
' Also run once in reverse to catch mismatching subfolder count:
Call SyncFolders(WshArgs.Item(1), WshArgs.Item(0))
Else
Wscript.Echo("Wrong number of arguments. Syntax: SyncFolders Folder1 Folder2")
Wscript.Sleep(3000) ' To allow Function syntax popup message to be seen.
End If
Sub SyncFolders(strFolder1, strFolder2)
Dim objFileSys
Dim objFolder1
Dim objFolder2
Dim objFile1
Dim objFile2
Dim objSubFolder
Dim arrFolders
Dim i
Set objFileSys = CreateObject("Scripting.FileSystemObject")
arrFolders = Array(strFolder1, strFolder2)
For i = 0 To 1 ' Make sure that missing folders are created first:
If objFileSys.FolderExists(arrFolders(i)) = False Then
wscript.echo("Creating folder " & arrFolders(i))
objFileSys.CreateFolder(arrFolders(i))
End If
Next
Set objFolder1 = objFileSys.GetFolder(strFolder1)
Set objFolder2 = objFileSys.GetFolder(strFolder2)
For i = 0 To 1
If i = 1 Then ' Reverse direction of file compare in second run
Set objFolder1 = objFileSys.GetFolder(strFolder2)
Set objFolder2 = objFileSys.GetFolder(strFolder1)
End If
For Each objFile1 in objFolder1.files
If Not objFileSys.FileExists(objFolder2 & "\" & objFile1.name) Then
Wscript.Echo("Copying " & objFolder1 & "\" & objFile1.name & _
" to " & objFolder2 & "\" & objFile1.name)
objFileSys.CopyFile objFolder1 & "\" & objFile1.name, _
objFolder2 & "\" & objFile1.name
Else
Set objFile2 = objFileSys.GetFile(objFolder2 & "\" & objFile1.name)
If objFile1.DateLastModified > objFile2.DateLastModified Then
Wscript.Echo("Overwriting " & objFolder2 & "\" & objFile1.name & _
" with " & objFolder1 & "\" & objFile1.name)
objFileSys.CopyFile objFolder1 & "\" & objFile1.name, _
objFolder2 & "\" & objFile1.name
End If
End If
Next
Next
For Each objSubFolder in objFolder1.subFolders
Call SyncFolders(strFolder1 & "\" & objSubFolder.name, strFolder2 & _
"\" & objSubFolder.name)
Next
Set objFileSys = Nothing
End Sub
Sub ForceScriptEngine(strScriptEng)
' Forces this script to be run under the desired scripting host.
' Valid arguments are "wscript" or "cscript".
' The command line arguments are passed on to the new call.
Dim arrArgs
Dim strArgs
For Each arrArgs In WScript.Arguments
strArgs = strArgs & " " & Chr(34) & arrArgs & Chr(34)
Next
If Lcase(Right(Wscript.FullName, 12)) = "\wscript.exe" Then
If Instr(1, Wscript.FullName, strScriptEng, 1) = 0 Then
CreateObject("Wscript.Shell").Run "cscript.exe //Nologo " & _
Chr(34) & Wscript.ScriptFullName & Chr(34) & strArgs
Wscript.Quit
End If
Else
If Instr(1, Wscript.FullName, strScriptEng, 1) = 0 Then
CreateObject("Wscript.Shell").Run "wscript.exe " & Chr(34) & _
Wscript.ScriptFullName & Chr(34) & strArgs
Wscript.Quit
End If
End If
End Sub
I changed the :
Sub SyncFolders(strFolder1, strFolder2)
to
Sub SyncFolders(strC:\Users\Zac\Desktop\Folder, strW:\Folder)
and get the error "Expected ')'
I'm sure it's something very obvious, but could someone please tell me what I need to change in that script to make my folders mirror each other?

Since this vbscript force to deal with Cscript engine; you should execute it by a litlle batch like this way :
#echo off
Cscript /nologo SyncFolders.vbs "C:\Users\Zac\Desktop\Folder" "W:\Folder"
pause
Edit :
And if you like to avoid this batch and using Cscript engine,try this :
Option Explicit
'You must only change the absolute paths of the two folders here
Call SyncFolders("C:\Users\Zac\Desktop\Folder","W:\Folder")
'**********************Don't Change nothing below this line *****************************
Sub SyncFolders(strFolder1, strFolder2)
Dim objFileSys
Dim objFolder1
Dim objFolder2
Dim objFile1
Dim objFile2
Dim objSubFolder
Dim arrFolders
Dim i
Set objFileSys = CreateObject("Scripting.FileSystemObject")
arrFolders = Array(strFolder1, strFolder2)
For i = 0 To 1 ' Make sure that missing folders are created first:
If objFileSys.FolderExists(arrFolders(i)) = False Then
'wscript.echo("Creating folder " & arrFolders(i))
objFileSys.CreateFolder(arrFolders(i))
End If
Next
Set objFolder1 = objFileSys.GetFolder(strFolder1)
Set objFolder2 = objFileSys.GetFolder(strFolder2)
For i = 0 To 1
If i = 1 Then ' Reverse direction of file compare in second run
Set objFolder1 = objFileSys.GetFolder(strFolder2)
Set objFolder2 = objFileSys.GetFolder(strFolder1)
End If
For Each objFile1 in objFolder1.files
If Not objFileSys.FileExists(objFolder2 & "\" & objFile1.name) Then
'Wscript.Echo("Copying " & objFolder1 & "\" & objFile1.name & _
' " to " & objFolder2 & "\" & objFile1.name)
objFileSys.CopyFile objFolder1 & "\" & objFile1.name, _
objFolder2 & "\" & objFile1.name
Else
Set objFile2 = objFileSys.GetFile(objFolder2 & "\" & objFile1.name)
If objFile1.DateLastModified > objFile2.DateLastModified Then
'Wscript.Echo("Overwriting " & objFolder2 & "\" & objFile1.name & _
' " with " & objFolder1 & "\" & objFile1.name)
objFileSys.CopyFile objFolder1 & "\" & objFile1.name, _
objFolder2 & "\" & objFile1.name
End If
End If

Next
