¿cómo puedo comprobar si existe un archivo?
Quiero comprobar si existe un archivo y si lo hace, quiero abrirlo y leer la 1ª línea,
Si el archivo no existe o si el archivo no tiene contenido, entonces quiero fallar silenciosamente sin que nadie sepa que se ha producido un error.

Comience con esto:
Set fso = CreateObject("Scripting.FileSystemObject")
If (fso.FileExists(path)) Then
msg = path & " exists."
Else
msg = path & " doesn't exist."
End If

Para cualquiera que esté buscando una manera de ver que un archivo específico exista en 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
Uso:
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

Una carpeta existente FALLARÁ con FileExists
Function FileExists(strFileName)
' Check if a file exists - returns True or False
use en su lugar o además:
Function FolderExists(strFolderPath)
' Check if a path exists
