Solution Documentation: Documents location

Hi Experts,

When i have uploaded the document in solution Documentation, where exactly i can find the same document in backend system. What is the tcode to reach there and Is there any way to download. (As now we are downloading from frontend screen, UI5 screen).

Problem: We have many duplicate document in the system. We created new BPH structure for the same. Now Old Specific documents needs to map to new structure. As we have thousand of documents, we need to know the files location.
