How can i get the complete tree view of entire sharepoint documents just like site map or explorer

Now here’s the case, i just recently joined a company with the task of PMO have been assigned the task to clean up the companies sharepoint user portal. With almost anything and everything been uploaded in the sharepoint by the developers (as the evidence of the meeting etc.) the documents are no more needed after specific period of time.

Since there are exhaustive list of documents that needs to be gone through. its little difficult to keep the note of the documents which are to be removed (remember im preparing the note of document to be removed and get the approval and then the archiving would happen)

So for this i just need to get the tree view of the entire documents structure(hierarchy) so, i could take a printout of the view and could give the appropriate note against it.

The point here is been the user im not quite sure wether that feature is available in sharepoint or do we have to get in touch with the company’s sharepoint dev team.
