Is there a way to have a Document Library WebPart open to a specific folder?
I've been playing around for a few hours and I don't see a decent option.
Adding to jkandiko's answer (which worked for me),
If the URL of the page containing your document list web part is
http://www.mySharePoint.com/SitePages/Home.aspx, append the text
?RootFolder=((Path to target folder)) to this URL.
?RootFolder=((...)) can be found by navigating to the target folder in the document library, then checking the resulting URL.
I've been able to get document list web parts to open to a specific folder by changing the URL. If you put RootFolder=PATH, the document library will open to that folder. The problem is, it does it for all libraries on the page. But maybe this will get you in the right direction:
RootFolder=/PATH/TO/Shared Documents/FOLDER NAME
I have found a way to accomplish something similar.
All the files are not in the same Document Library, but you can manage them in one place using the Site Contents view.
