Access SAP file through OAPI without opening the file

[darkjmf1]

Hello,
I know how to access a SAP file through the OAPI from VBA, e.g.:

Set ObjetoSap = New SAP2000v16.SapObject
Set ModeloSap = ObjetoSap.SapModel
ObjetoSap.ApplicationStart
ret = ModeloSap.InitializeNewModel
ret = ModeloSap.File.OpenFile(txt_fichero.Text)

Here I include the code needed to read whatever I need from the SAP file​

ObjetoSap.ApplicationExit (True)
Set ModeloSap = Nothing
Set ObjetoSap = Nothing​

My question is simple: How could I access the information included in the SAP file without opening such file or even opening the program?

My first approach would be something like:

Set ObjetoSap = New SAP2000v16.SapObject
Set ModeloSap = ObjetoSap.SapModel
ret = ModeloSap.File.OpenFile(txt_fichero.Text)

Here I include the code needed to read whatever I need from the SAP file​

Set ModeloSap = Nothing
Set ObjetoSap = Nothing​

Unfortunately it is not working.
Am I asking for something impossible? If not, could somebody help me in the right direction?
Thanks in advance.
