Hi,

I would like to rename all files in a folder by removing the first 13 characters of each file name. I have written the following VBScript however it fails - can anyone help?

strComputer = "."
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colFiles = objWMIService.ExecQuery("Select * from CIM_DataFile where Path = '\\Documents and Settings\Administrator\My Documents\NDS\Test\\'")
Set objFSO = CreateObject("Scripting.FileSystemObject")

For Each objFile in colFiles
      strOldName = objFile.Name
      Msgbox strOldName
      strNewName = Mid(strOldName,13,strOldName.Length)
      objFSO.MoveFile strOldName,strNewName
Next

it failes because in the MoveFile, you do not specify the path, only the name:

strComputer = "."
strPath = "\\Documents and Settings\Administrator\My Documents\NDS\Test\"
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colFiles = objWMIService.ExecQuery("Select * from CIM_DataFile where Path = '" & strPath & "' ")
Set objFSO = CreateObject("Scripting.FileSystemObject")

For Each objFile in colFiles
     strOldName = objFile.Name
     Msgbox strOldName
     strNewName = Mid(strOldName,13,strOldName.Length)
     objFSO.MoveFile strPath & strOldName, strPath & strNewName
Next

I am now getting a null error on line 7. The folder which contains the files is:

C:\Documents and Settings\Administrator\My Documents\NDS\Test

is this the problem?

putting the entire path might help:

strComputer = "."
strPath = "C:\Documents and Settings\Administrator\My Documents\NDS\Test\"
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colFiles = objWMIService.ExecQuery("Select * from CIM_DataFile where Path = '" & strPath & "' ")
Set objFSO = CreateObject("Scripting.FileSystemObject")

For Each objFile in colFiles
     strOldName = objFile.Name
     Msgbox strOldName
     strNewName = Mid(strOldName,13,strOldName.Length)
     objFSO.MoveFile strPath & strOldName, strPath & strNewName
Next

I see. the drive needs to be in separate condition, and the path needs double backquotes everywhere:

strComputer = "."
strPath = "\\Documents and Settings\\Administrator\\My Documents\\NDS\\Test\\"
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colFiles = objWMIService.ExecQuery("Select * from CIM_DataFile where drive='C:' and Path = '" & strPath & "' ")
Set objFSO = CreateObject("Scripting.FileSystemObject")

For Each objFile in colFiles
     strOldName = objFile.Name
     Msgbox strOldName
     strNewName = Mid(strOldName,13,strOldName.Length)
     objFSO.MoveFile strPath & strOldName, strPath & strNewName
Next

I now get an error for line 9 (strNewName = Mid(strOldName,13,strOldName.Length)) which says it cannot find the strOldName variable even though i have declared it in line 7 - any ideas?

please try this:

strComputer = "."
strPath = "\\Documents and Settings\\Administrator\\My Documents\\NDS\\Test\\"
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colFiles = objWMIService.ExecQuery("Select * from CIM_DataFile where drive='C:' and Path = '" & strPath & "' ")
Set objFSO = CreateObject("Scripting.FileSystemObject")

For Each objFile in colFiles
     strOldName = objFile.Name
     Msgbox strOldName
     strNewName = Mid(strOldName,13)
     objFSO.MoveFile strPath & strOldName, strPath & strNewName
Next


strOldName.Length does not exist in vbscript, only in vb.net

you don't need that. if you leave the length argument out, it will take the rest, whatever length remains.
