vbs - 800a0046 - Ignore running files and folders.

Question

I need to clear Caches: files and folders.
But sometimes there are files and folders that are in use, I think this produces the error: “800a0046” permission denied.
I want that if a file or folder is in use, the code will skip it and continue with the next one files and folders.
I accept alternatives.
(Excuse my google english)

-------------------

Set objFSO = CreateObject("Scripting.FileSystemObject")  
  
rute1 = "C:\Windows\Temp\"  
  
rute1existe = objFSO.FolderExists(rute1)  
  
if (rute1existe) then  
 Const DeleteReadOnly = TRUE  
 objFSO.DeleteFile rute1 & CurrentDirectory & "\*", DeleteReadOnly  
 'objFSO.DeleteFolder rute1 & CurrentDirectory & "\*", DeleteReadOnly  
 else  
 msgbox "error"  
end if

Necesito borrar Caches: archivos y carpetas.
Pero a veces existen archivos y carpetas que se encuentran en uso, creo que esto produce el error: “800a0046” permission denied.
Quiero que si un archivo o carpeta se encuentra en uso, el código lo salte y continúe con los siguientes archivos y carpetas.
Acepto alternativas.

In VBS, to handle errors you'll need to use On Error Resume Next.

   On Error Resume Next  
      Do something that can fail  

If you want to actually do some processing on error then you'll need to use a label.

   On Error Resume HandleError  
      Do something that can fail  
   HandleError:  
      Do something in case of failure  
   Resume Next  

For deleting files that may be in use note that if you attempt to delete the entire folder then it'll fail but some files may already be deleted. If you want to delete as many files as you can then you'll need to enumerate the files instead (including their subfolders). For that you'll need to walk all the child folders in the parent folder and then enumerate all the files in each child folder (and they can recursive indefinitely). For each file try to delete it. If a folder is empty then you can remove the folder itself otherwise the folder remains and you move on to the next folder.

Here's a link to a Stack Overflow post where a person has provided that code. They even seem to have the error handling code in place although I don't know if you need the calls to Echo yourself.
