Where are stored electronical documents attached from PC

Hello,

I'm working on the Archive link and attachment link to SAP object as outgoing invoice (VF02), incoming purchase order (ME22N).

We have implemented a SAP content repository.

I well understood when I attach a document with "Store business document" (Toolbox at the bottom left of VF02 for example), this document is physically stored in a server dedicated to the repository.

I have a problem to find where the document is stored when I attach a document from PC "Create attachment" in toolbox.

I found the table SOOD which gives an ID for my linked document but I don't know where this document is physically copied from PC to SAP

If someone has the answer it would be great !!

thanks for your help.
