For anyone who is looking a way to watch a specific file to exist in VBS:

Function bIsFileDownloaded(strPath, timeout)
  Dim FSO, fileIsDownloaded
  set FSO = CreateObject("Scripting.FileSystemObject")
  fileIsDownloaded = false
  limit = DateAdd("s", timeout, Now)
  Do While Now < limit
    If FSO.FileExists(strPath) Then : fileIsDownloaded = True : Exit Do : End If
    WScript.Sleep 1000      
  Loop
  Set FSO = Nothing
  bIsFileDownloaded = fileIsDownloaded
End Function

Usage:

FileName = "C:\test.txt"
fileIsDownloaded = bIsFileDownloaded(FileName, 5) ' keep watching for 5 seconds

If fileIsDownloaded Then
  WScript.Echo Now & " File is Downloaded: " & FileName
Else
  WScript.Echo Now & " Timeout, file not found: " & FileName 
End If
