VBScript to run a robocopy command

Posted on 2010-08-22
Last Modified: 2012-06-21
Hi All,

I'm trying to run a robocopy command within a VBScript which isn't producing an error, but isn't completing the required file copy either. I need to use VBScript as a list of folders must be iterated through.

On Error Resume Next
Set oShell=WScript.CreateObject("WScript.Shell")
Set objFSO = Wscript.CreateObject("Scripting.FileSystemObject")
WScript.Run("robocopy" & " " & Chr(34) & "C:\source\folder one" & Chr(34) & " " & Chr(34) & "C:\dest\folder one" & Chr(34) & " " & "/e /xo /mir /zb /R:5 /W:5 /LOG+:" & Chr(34) & "logs\folder one.log" & Chr(34))

Open in new window

This code works if the source and destination dirnames lack spaces. Any ideas?

Firstly tho - take out that beginning line - on error resume next - you're masking any errors, preventing you from telling what's not working.
Try this:
Set oShell=WScript.CreateObject("WScript.Shell")
'(Do you even need FSO?) Set objFSO = Wscript.CreateObject("Scripting.FileSystemObject")
strSource = Chr(34) & "C:\source\folder one" & Chr(34) 
strTarget = Chr(34) & "C:\dest\folder one" & Chr(34) 
strParms = " /e /xo /mir /zb /R:5 /W:5 /LOG+:" & Chr(34) & "C:\logs\folder one.log" & Chr(34)
oShell.Run "robocopy " & strSource & " " & strTarget & strParms

sirbounty....long time no see....I hope you're keeping well.

The original script looks like it would have worked, only if the WScript.Run was changed to oShell.Run, but either way, sirbounty's is a bit more managable.

use oShell.Run "%comspec% /k robocopy " & strSource & " " & strTarget & strParms to keep the Cmd box open if the script is erring

If, like me, you're not a big fan of using a bunch of & Chr(34) & (the ASCII code for a double-quote) then you can just insert a double-quote mark inside a string using a double double-quote ("") when you create the string.

an edit of sirbounty's rewrite using double double-quotes would look like this:
Set oShell=WScript.CreateObject("WScript.Shell")
'(Do you even need FSO?) Set objFSO = Wscript.CreateObject("Scripting.FileSystemObject")
strSource = """C:\source\folder one"""
strTarget = """C:\dest\folder one"""
strParms = " /e /xo /mir /zb /R:5 /W:5 /LOG+:""C:\logs\folder one.log"""
oShell.Run "robocopy " & strSource & " " & strTarget & strParms

Yes, there's THREE double-quotes in there in some spots and only a single actual "double double-quote" but that's because a string is always started with a double-quote and ends with a double-quote.  The "triple double-quotes" are actually a "single double-quote" immediately followed by a "double double-quote" to start the string with a double-quote at the beginning of it and vice-versa to end the string with a double-quote at the end of it.

How's that for technological double-speak?
