Create a webpart to show subfolder of existing document library

Hi

As above I have a document library called 'Test' that has 10 folders in it and various files in each folder.

I now want to create a web part of some kind on a page in my site, but have it display as a webpart and defaulting to the contents of folder C that is within 'Test'

For some reason the web part only displays the document library as a whole and causes the user to navigate to C within the web part - how can use the full link of folder C as the default of the web part?

I'd prefer to not do this in sharepoint designer as I have no experience with it and would have thought this is something that you could easily achieve.

Thanks
